Aliens are obviously real.

Man says life only grow on Earth because only Earth has water, fundamental to life on Earth.

Man go to moon. Find water on moon.

Man go to Mars. Find water on Mars.

Man research Jupiter, find water on its moons.

Man finds out the basic component to make life exists everywhere.

Going by the numbers, we will obviously find single cellular life on at least one other planet besides Earth.

The question then is, how likely are we to find intelligent alien life, or even primitive lion and tiger like alien life.

The answer is very likely.

Our galaxy alone has billions of Earth like planets. Earth like planets are those that can be found across the cosmos within the theoretical habitable zone for life to exist along with being similar to Earth's size.

Going by the numbers there is very obviously other intelligent life in the universe.

The question then is, why haven't we made contact yet.

Taking into account amount of time the universe and other galaxies have existed for, alien life must have already emerged by now in other places, with some civilizations far more advanced than us and others far less.

The answer to this question is simple, it's because technologically they are in a similar spot to us if they exist right now.

Here is why this makes sense.

The Earth is 4.5 billion years old. The oldest planet in the galaxy is 9 billion years old. Life on Earth started 3.7 billion years ago.

It took 3.7 billion years of random permutations in evolution to stack up to something as advanced as us humans. Who are still barely advanced enough to move from planet to planet.

The average age of a planet in the galaxy is similar to Earth's.

Assuming that all the other advanced civilizations are of a tech level similar to us, they are themselves yet to conquer their own solar system. If we look at our own solar system, it would take us at least thousands of years to colonize the entire solar system, and this is if we were doing it in earnest.

Mars itself would take thousands of years to fill up to optimum population capacity in a best case population boom scenario. That's just two planets within the same solar system. Similarly other advanced species would take hundreds of thousands of years to have any utility in moving from solar system to solar system.

The real question is, why haven't we gotten any signals from other intelligent life in the galaxy?

One possibility is that it is because the distances are too vast and space too big for a signal to reach the right place at the right time. Our own furthest radio signals are incapable of covering even a 10th of the Galaxy, and even if another intelligent civilization has received the signal, it would take equally long for them to respond and for us to receive the signal, not even taking into account that the signal might not be disclosed to the public.

Another is that they just don't care about alien species so far away. It's hard enough for us humans to care about even what is happening half a planet away, it might be almost impossible to hold interest for events occurring 10-20 light years away.

Conclusion:

Aliens obviously exist. We should conquer the stars. it is man's divine destiny. We should start with the moon, Mars, and giant mining rigs on asteroids in our own solar system.

Humans will see a population boom the moment more land opens up to them and robotics replaces slave labor/ current day workforce.

We are nearing the next great population boom.

This post rests on native land.
