Three things are certain:

1 We are not alone

evidence supporting that statement?

2 Intelligent life that has been around more than a million years
is aware of us.

Define intelligence. Bees? Cockroaches?

3 Earth has been visited; I said Earth - not us!

Evidence supporting that statement?

Your definition of "certain" leaves a lot to be desired.

Bingo.
