That would be a false assumption. What if an alien species' average lifespan was billions of years? Coming to Earth for a visit could be like going on a month long safari vacation to them even though it takes millions of years to get here.Then your also talking out of your ass.then you're speaking out of your ass. If such entities existed you have no idea what technology they'd have that we are unaware of -- unknown unknowns.I just don't think any intelligent being from another world could get to us.
That said, Dante does not believe we;ve been visited
What do you mean we have no idea? We know that any other world is incredibly far and we know we don't possess technology that can get us to them so we can assume neither do they.
