Has anyone every met an alien from outer space for real?

No. No one has ever met an alien from outer space for real. All alien meetings, abductions, etc. are all delusions caused by well-defined psycological reasons, or they are hoaxes.

Yessssssssssss. His name was Rico, he from Mexico, he my neighbor.

have you ever heard about old hiuge
i spelt hiuge wrong but its a woman who worships the demons and she becomes a ball of fire when the night come and goes and sucks people blood out

No

Who knows. Its possible.

So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.

Why haven't we heard from them?

Perhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.

Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.

Perhaps they are so far away they will never notice us and vice versa.

Perhaps they existed a million years ago and died out.

Perhaps they will exist a million years from now.

It is really impossible to know for sure.

The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.
