If Aliens Exist.

If i consider the title - Aliens DO exist! Whether microscopic or intelligent in nature they exist! Absence of proof is not proof of absence. We would be naive to think that this earth, as truly insignificant as it is in the bigger scheme of things, is certainly not the only body with life of any sort.

Secondly, most planets or life bearing bodies are probably in the same boat as us and "searching"...

Those that DO travel here (UFOs) lets say they do are WAY more advanced and could probably wipe us out VERY easily OR turn us into a slave nation (again )

Perhaps they are done with us. Consider too that genetic engineering is probably old hat to them and they walk amongst us.
