Are aliens real? even though we do not have the complete evidence, it is very likely they are.

see, every solar system has one star (some have 2, those are called binary systems!),
and the milky way alone has an estimated 100 thousand million (100,000,000l stars,
and every star in the universe is predicted to have at least one planet orbiting it.

that's only in this galaxy we live in, and ours isn't even one of the largest!

so, with at least one planet orbiting every star, that means that there are over 100 thousand million planets, just in our galaxy!

with that many planets, there is an extremely slim chance that life isn't out there, especially since just in our solar system, we have another planet (mars), that could've possibly held water in it. and as you know, if there is water, there is life.

so with that being said, the only question is, why haven't they found us yet?

well, that's think about this, why haven't we found them yet? for all we know, the life outside of this solar system could be Dinosaurs. now do you think a dinosaur has enough brains and the ability to create a spacecraft that could fly to different galaxies or even a light year away?

it would take a human 37,000 years just to travel one light year.

so in conclusion, the possibility fo there being life out there is very likely, but the possibility of us ever seeing each other is very slim, well, at least for a couple of centuries, as NASA believes they have discovered warp drive, but haven't found a particle which could allow us to travel fast enough. but given the amount of advancements we made in a short time (100 years [from a horse buggy to gas now electric powered cars, large television larger than your head to a mini all in one device capable of being a TV as well, aka a phone.]) it is possible that we could be traveling farther than just the moon one day.
