I believe aliens are real. I mean, we're not the only habitable planet out there I'm sure, so there's got to be beings like us out there, or even better or more messed up than us. But there's got to be other beings out there who are like humans and can think, feel, speak, etc. I think it'd be cool to one day discover a planet we can actually reach that has life. Obviously it would be scary, but exciting at the same time. What do you think we'd see. What will beings look like on other planets.
Honestly, I'm kinda hoping there are other planets with humans. What if that was a reality, that other planets had human like beings, kinda like Star Wars. But I don't think it's as cool as that.
Here is my thought.
There are nearly an infinite number of planets out there. How many are habitable I don't know but I'm sure it is a large number.
Now if you look at the science here on Earth in the grand scheme it didn't take much of the life of the planet for life to develop and not long after that for intelligent life to develop. Initially the planet was too hot for life to develop, but as soon as things cooled down life developed pretty quicky.
Now I'm sure there are at least some habitable planets out there that have the same or a similar story. A lot of my theories exist around interstellar travel and the ability to achieve it.
There are a few possibilities. One is that if there is life out there, they are similar to us and don't have the ability to reach us. Another on this same theory is that life is out there but interstellar travel is either impossible or has not been able to be achieved by any civilization yet.
A second possibility is that there is life out there and they have achieved the ability of interstellar travel and could reach us. If such a life form exist they are far more advanced than us because we are no where close to interstellar travel. Two possibilities exist on this in my opinion. First is that such a life form would simply wipe us out and there wouldn't be much we could do to stop them. They would be so much more advanced that there would be little we could do to fight them. Second possibility is that such a life form is so much more advanced than us that they have no interest in us. They probably wouldn't even consider us to be intelligent life. They may have came here already saw us as a primitive useless form of life not worthy of interacting with and kept on moving. They saw us the way we see bacteria.
The third overall possibility is that there is no other life out there at all. Earth has been the only planet amongst trillions that developed life.
If you believe in God and want to see it from a theological point of view then this would mean that God only saw fit to put life on Earth and nowhere else. He created the entire universe and only developed one form of life within it.
