If there were extra-terrestrial intervention, it would only have needed to be a one-time event.

And it wouldn't be technologically hard to do it such that no trace remains over those timescales.

So, yes, that's "crazy". On the other hand, it's unfalsifiable in the absence of other theories.

The burden of proof is on the person making the claim. It is not on someone else to disprove such a claim.

There are much saner theories for panspermia.

Like? You're coming across as very dismissive for no reason.

There are meteorites on Earth which very likely originated from Mars. They're believed to have been launched into space by an impact, eventually finding their way onto Earth. If we're looking for the most realistic options for panspermia to have occurred, they'd be due to a natural event of this sort.

It’s very much like how islands in the sea are colonized by life. Some event causes a blob of living creatures to enter the sea on a raft and they drift until they make landfall somewhere else. Sometimes they survive long enough in the new place to reproduce.

I'm not arguing against that.

I'm just saying unfalsifiability is a bitch, and it's hard to find hard evidence on geologic timescales.
