Saying that life on Earth came from another planet, simply kicks the can down the road.
Where did THAT life come from?
And if you say another planet, then where did THAT life come from?
It’s a non-answer, and a way for a ‘scientist’ to avoid answering the obvious.
There is absolutely no evidence of life outside the Earth’s sphere of influence. None, zero, zip, nada.
If there were, it would be everywhere...........................

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.
Agree...except about the “everywhere” comments. But we should find the signature of life quite readily on other planets if it is that easily produced. Yes, the idea that life forms by abiogenesis is very, very, farfetched, yet is always assumed to have happened with no proof at all.
