Until we solve the missing fundamental forces of the universe we don’t know enough to speculate on other life forms.

If the SOL is a limit for physical travel then it’s just irrational for a civilization to do other than grow by rate of colonization.

If SOL is a limit to communication then communication has no value. If SOL is not a limit for communication, then we can’t likely see/hear anything.

So age of the universe plus demands upon planetary stability over time, plus SOL open questions, means …. hard to know until we get there ourselves.

Resources are not a reason to seek planets. Trade is very unlikely to be a reason to seek planets. Colonization is the only caloric reason that makes any sense.

Hence mechanical probes are the only valuable contact other than conquest, extermination, and replacement.

My intuition is that if life exists out there and can defeat the SOL or time problems, even if purely mechanical, then they’ve been here already.
