My own opinion is that any ET that exist is way too far from our solar system to ever get here.

Have you ever heard of space wormholes?

“Have you ever heard of space wormholes?”

Yes, of course. Worm holes, folding and parallel universes are the favorite claim of the UFO crowd. It is about the only concept that they now have, but it leads to nothing.
To my knowledge, none of it has been proven.
Even if it is true, it still does not mean that we are, or ever have been visited.
Get back to me when one lands in public and the occupants
say “Take me to your leader”.

Yes space worm holes, I doubt that anything on Earth could survive a trip through one. Providing that they exist at all!
