Aliens from "outer space".......do you believe?

[BYoNexus]

How about: Yes they exists. No I dont believe they've been here. The evidence is circumstantial at best.

But by Drake's Equation... Even if you edit it to be even more remote... It still leaves >1 planet with intelligent life on it.

So unless one of these species spent generations to come to our world, and just "observe" us, the chances that they've actually been here is slim.

UFOs? Just unidentified, not necessarily alien.
