Sure! They've been coming here for thousands of years !
I'm here 🐉 ;)
There most likely is life on other planets already.
This reminds me of a quote.
"To the maggots in the cheese, the cheese is universe
To the worms in the corpse, the corpse is the cosmos.
How then can we be so sure of world.
Just because of our telescopes and microscopes and the splitting of the atom.
'There are more things in heaven and earth then can be dreamt of in our philosophies'
Do we know what's beyond?
Do we know what's behind the beyond?
Some of us hardly know what's beyond the behind."
they are already here. My cat controls me they are all disquised as pets but they are aliens and we are under their control
