Honestly why doubt it?

I do believe there is other life in outerspace. Space is so vast and infinite how can we say there isn't? As of now there is no actual way to see if other life does excist out there, its just too far away. Theres so many galaxies, in space our galaxy is like a speck of sand on galveston beach. I do beleive in aliens, and I also beleive someday they will come to earth. Whether it's in my lifetime I dont know, but it would be amazing thing to witness. Ive watched countless documenteries about space, ufo's, aliens, and they have me convinced. I just cant ignore what's infront of my face.
