Aliens and space, are there aliens in the space of the world?

Actually, I've thought about it too.

But we're just a little human being.

There are many things that we don't just want to know.

Probably yes.

And look at us ignorant humans where we don't know.

All I can tell you is that only God knows.

There may be so-called parallel universes, where as long as the atmospheric composition is close to the Earth, it is suitable for human existence.

Aliens are inevitable.

Nowadays, people mainly live on other planets or moons, but some people hypothesize that there may be special life forms on stars (which are absolutely completely different from terrestrial life, they are not even made of elements in the usual sense), and even aliens may exist in space.

There are two main possibilities for aliens living in space: First, those aliens originally had their own home planet, but for some reason they left the home planet and wandered around the universe in a spaceship. Second, those aliens were born directly in the universe.

Such life forms are also obviously very different from life on Earth. They may even be just collections of information mediated by certain particles in the universe (i.e., some kind of so-called spiritual life).

Aliens may also exist on Earth. Leaving aside the controversial reports of so-called alien sightings, let's talk about the possibility. Humans don't actually fill every corner of the earth, which makes it possible for aliens to hide on the planet.

They can hide deep in mountains and forests, they can hide under the sea, and even they can hide in the center of the earth (some theories suggest that the earth is hollow).

Earth is just a small planet in one of the galaxies in the universe. How many galaxies are there in the vast universe? There must be planets like Earth.

Are there any aliens? According to the Fermi paradox proposed by the famous Nobel laureate Fermi, if there are aliens, then they may have come to Earth and exist somewhere, but they just didn't communicate with us, maybe our technology is too backward to detect them; Or that there is no other civilization in the universe.

Say the Earth, the Solar System, the Milky Way, what Orion, Ursa Major, this and that, Libra, Aquarius, how vast are these ranges, so vast that you have fresh water on Earth, you have life on Earth, people don't have it, it's unlikely.
