Except we already found exoplanets and this isnt any different besides the fact thats its 4LY's away wich is still a long loving distance.
And if you think extraterrestrial life doesnt exist your ego is bigger than the entire loving universe. Its loving obvious theres life outside this planet with a little bit of common sense.
The scientific community is still torn on whether or not life must exist elsewhere.
By a pure numbers game it seems likely that there would be life out there, or that there has been life out there.
But we have no idea what the chances even are of life starting, given ideal conditions, so no one can be certain. And just because something is statistically likely it doesn't guarantee that it's true.
It's a pointless exercise to profess either view as certain without any further evidence.
