Does Extraterrestrial Life Exists?

A theory without evidence, but using logic.

It is a question that has no definitive answer, or does it? We will find out if we reach a logical conclusion. We’ll never know what is occurring on in the vastness of the universe and time, but we can reason. A theory without evidence, but using logic.

First, let’s define extraterrestrial life.

We can identify two types: intelligent and non-intelligent.

Let’s start with the unintelligent.

There is a hypothesis suggesting that terrestrial life comes from space, which arrived on our planet in the form of microorganisms.

There are microorganisms and spores that are capable of surviving in outer space.

It has also been demonstrated they are capable of resisting the temperatures involved in entering the atmosphere.

This is the pan-spermia hypothesis.

It might explain how life began on this planet, but it would not explain the beginning of life in the universe.

This theory does not prove extraterrestrial life because all the tests were made with terrestrial microorganisms.

It is interesting to know if these life forms exist or not.

It would not change in our day to day life to know if there is microbial life floating around in the universe.

What it would change is the explanation of how life began on our planet.

If a meteorite ever falls with alien bacteria, it would be the first time we would have a reasonable explanation, with scientific evidence, of a probability of how life began on this planet.

It would be a shift in consciousness.

In answering this question, a bifurcation occurs.

There are on this planet bacteria and fungal spores capable of surviving in space; they are capable of surviving the journey into the atmosphere of a planet like ours.

As Albert Einstein said: god does not play dice.

This means that nothing is random, and that everything has a purpose.

There is an axiom that states something like this: Everything that can happen will happen.

It is the famous Murphy’s law; well, it’s well known among industrial designers.

Eventually, the sun will implode and destroy our planet.

It is likely that microorganisms of our planet will survive that event and will float on bits of the planet no wider than 1 square centimeter.

Meteorites.

Even if our solar system disappears, some terrestrial life will survive floating in space.

All the evidence points to that.

The question is: why can life survive such an event?

Exactly, so that it does.

Then, life that survives would cease to be terrestrial life and would become floating universal life.

Until it finds another planet, if it happens.

Considering the vastness of the universe and the probabilities of planets like ours, knowing there are bacteria capable of surviving in space, the most logical conclusion would be that there is reason for universal life in the universe to exist.

If what I propose is correct, we can also conclude that terrestrial life does not exist.

What I mean is that the concept of terrestrial life does not exist: it is universal life adapted and developed on a random planet.

Now on planet Earth.

Life is universal: it is linked to the universe and not to a planet.

Life in the universe is the only one created and spread throughout the universe, and when the right conditions exist, it develops.

It adapts to the environment.

There is a common ancestor of all human beings, we are one extensive family.

All mammals, including us, have ancestral relatives.

All plants also have a common ancestor.

All plants and animals, dating back, also have a common ancestor.

All our evolution, the scientific evidence, can be found in each other’s DNA, but also in that of animals.

That information is deducible and traces all the way back to the origin of life.

Life did not begin with the creation of this planet, but much earlier.

Life is linked to the universe and not to a particular planet.

But well, that still doesn’t answer the initial question.

To answer, we could rephrase the question with something measurable, such as what is the probability of two rocks colliding in our universe?

First, we must determine the size of the universe.

The size of this is difficult to imagine.

It is said that for every grain of sand on this planet there are a million stars.

Probably more.

There are hundreds of billions of galaxies like ours.

And that is just the observable universe.

The matter in the observable universe is estimated to be only 5% of the entire universe.

We can say that the universe is infinite for us, because we simply cannot measure it, nor imagine what limits it could have.

Let us consider only the observable universe.

A light year is the distance light travels in one year traveling at the maximum speed of 300000 kilometers per second.

A light year is 9.46 trillion kilometers.

We estimate the limit of the visible universe to be 46500 million light years in all directions.

Suppose we are playing marbles.

You have a 2 by 2 meter court and you have two marbles.

You throw the first one into the center of the court, or so you try.

The marble lands randomly.

With the second marble, you try to hit the first one, throwing it from outside the court.

Difficult but not impossible.

You must throw the second marble blindfolded, not knowing where the first one landed, in order to compare accordingly.

What is the probability of collision?

Would you bet on that game?

No, because you would lose every time.

Now imagine the playing field is the observable universe.

And planet Earth is the first marble.

And meteorites, the size of dice, carrying bacteria or spores, scattered in the universe.

Is it possible that they will ever collide?

It’s not possible.

Or at least, it’s ridiculous to wait for it to happen in the time of humanity.

It’s impossible for us to find universal life floating around.

The answer to the initial question is we’re never going to find unintelligent extraterrestrial life.

I’m not saying it can’t exist.

We will never find evidence it does.

It is impossible because of the vastness of the universe and the short time we have as humanity.

Now for the second variety of extraterrestrial life: intelligent.

In this case, the vastness of the universe plays in favor of the possibility that intelligent life exists outside this planet.

The basis of the theory would be the same: panspermia.

For now, it is the most logical explanation of how life spreads in the universe.

Or it could spread.

So, the wider the universe, the more habitable planets can exist.

And, the more planets with the right conditions exist, the greater the probability of a small meteor with bacteria colliding with one.

— But now you tell me the opposite of the marble example.

In that case, you said it was impossible for two marbles to collide.

Let me explain.

The difference is that one of the marbles is defined in time and space: our planet.

It is not a single marble to collide with, but hundreds of billions of robabilities.

In other words, it is more likely that some meteorite with life will collide with some planet with the perfect conditions to develop life.

Additionally, I count marbles with life conditions we don’t know about.

Not only those that resemble our planet, but also those that could develop life totally different from ours.

The most logical conclusion is that some form of intelligent life exists in the universe, either it has existed, or it will exist.

We conclude that life may exist outside our solar system.

The question is when?

And with that question, we start the second part of the initial question.

We will use logic to reach a conclusion.

We know that the theory of panspermia is possible, philosophically speaking.

But, it cannot be considered correct until we find evidence outside our system.

Which we have already deduced is impossible to happen.

We assume that if something is possible, it will happen at some point.

That is the key to the answer: when are we going to encounter extraterrestrial life?

The key to reaching a conclusion is between the time of existence of intelligent life and the infinity of time.

Planet Earth is about 4.5 billion years old and human conscious life is only about 10,000 years old.

Since humankind developed writing, I consider it conscious.

If we extrapolate how we treat our planet, humanity will not survive another 10,000 years.

Intelligent life is finite and relatively short in the life of a planet.

It is also estimated that in about 20,000 years there will be another ice age, which will affect all animals and plants.

Bacteria will survive.

It is not the end of life.

We are finite, life is not.

Intelligent life on a planet is like a blink of an eye in the existence of that planet.

That would be the ratio of life span.

Nothing almost.

It would occur with intelligent life forms on other planets.

Or with past intelligent life on this planet?

I still don’t understand why the planet is so old and we are babies.

I’ll have to philosophize with that idea.

The vastness of space and time perception.

To illustrate:

Let’s say you represent a galaxy.

Like the Milky Way.

Life is a blink of your eyes, from consciousness to extinguishment.

A friend represents another galaxy with intelligent life.

The question is: what is the probability of both blinking at the same time?

Basically, almost none, but it could be.

Let’s continue with the comparison.

Suppose you are both at home.

Your house represents the universe, and you are in different rooms.

How do you know if the other person blinked?

How do you know which room she is in?

And, how do you blink at the same time?

Even if you want to cheat and shout “now” when you start blinking, when the sound reaches the other person’s ears, your blinking is already over.

But the universe is not like your house: it is like planet Earth.

It is unreasonable.

Our existence is like an oxygen bubble in the ocean.

We will never encounter other life forms in our observable universe.

And what about beings that can travel sub-dimensionally?

Beings that travel faster than the speed of light?

Beings that go outside our concepts of dimensions?

Our observable universe is bounded by the speed of light.

That speed determines our time and space in the universe.

Nothing in our observable universe can travel at a higher speed.

We only perceive 5% of the universe, our observable universe, which has for us a beginning and an end.

To say that beings from outside our observable universe can come inside is the equivalent of saying that god comes to us.

That leaves out the logic of philosophy and the evidence of science.

It leaves out logical reasoning based on observations.

Final words:

Although to us the evolution of life seems like a long time, it is a blink of an eye compared to the universe.

We are trapped in the vastness of space and limited to the infinite present.
