Is it scientifically "productive" to speculate that aliens seeded the Earth with life, via rocket ships?

And who determines the benchmark and standard that defines productive?

It seems pretty subjective if you ask me.

No, it would merely beg the question.

I'm looking at first causes.

The rocket ship conjecture is a bit far out for my taste, but panspermia is alive and well as a hypothesis, but panspermia is alive and well.

A productive ide is one that generates research or which suggests research. After 203 years, we are still waiting for ID to generate research.
