are aliens and ufo's real?

Nope. Aliens and UFOs are hollywood fiction, designed to discredit religion and help set up the planned alien invasion hoax, which will come some time after the staged third world war between Zionism and Islam.

The moon landings were fake and we are definitely being lied to about the shape of the earth, although I am not sure whether the earth is flat or concave.

Rockets don't work in vacuums as there is nothing to push against.

Look at this picture of the LM on the moon. The ground underneath looks undisturbed, even though they used a thrust engine to slow their descent.

Aliens might be. We simply don't know at this point.

UFOs can be considered 'real' because we see things we can't identify... they may be as common as birds or the landing lights of an airliner, but they just look strange to someone seeing them...

Not that we have been able to prove.
