“There is absolutely no evidence of life outside the Earth’s sphere of influence. None, zero, zip, nada.”

We humans are so clever that we finally confirmed the discovery the first exoplanet in 1992.
Prior to that anyone who claimed there were exoplanets was a kook with “no evidence of exoplanets” at all.
Human ignorance is a very strong argument for human ignorance. It “proves” nothing else.
Absence of evidence is not evidence of absence.
That is a given.
But if there were some form of life outside the Earth, it would be ubiquitous and easily identifiable and practically in every direction we could look.
So far we have found none even though we have spent astronomical amounts of treasure in the search for it........

When the extraterrestrials show up I will invite them over to have dinner. Unless they want ME for dinner.
