Yes I do believe in aliens. There is a very huge chance that there are other life forms in the very vast universe of ours. Our planet is just a very small dot in our galaxy, and our galaxy is a very small dot in the whole universe. So I am 100% sure that there are other life forms aside from humans, in other words, aliens.

I think that it would actually be awesome if we get to meet an alien. Let's just hope that their weapons are not very advanced compared to our weapons so that if ever something bad happens, we can fight them.
