Well considering we’ve just found the potential for life 120 light years away and we are very limited in our scientific knowledge it’s hardly outlandish to suggest a civilisation 1000’s of years more advanced than us could find us and have the technology to get here could have done so.
The explanation you are seeking will be far simpler, I’m sure.
If you know how it’s possible to make information travel faster than light speed (which is what would be needed for aliens located hundreds or thousands of light years away to detect us) then there is a Nobel Prize waiting for you. If this is a case the. What are you doing wasting your time on here?
