Yes, but not on earth, somewhere in the galaxy without spaceships lol

to me, this is like the one ¨Do you believe in aliens?¨ ¨No¨ ¨Do you believe in god?¨ ¨Yes¨ ¨Have you ever seen aliens?¨ ¨No¨ ¨Have you ever seen god?¨ ¨No¨

I mean, If the astronauts didn't come into contact with the aliens, There might be proof that there's aliens out there in the galaxy, Y'know? Hiding from our sight. But they were never able to get in the earth cause of it's dome, If an asteroid breaks into the atmosphere and into the dome, It breaks through and hits the earth.
