Thoughts about ET

Isn't The Earth a fairly desireable chunk of Real Estate for the possibly recently-become-homeless escapees of a cosmic event?

IF there are Extraterrestrial Intelligent Beings, carbon based too (which is likely), and like therefore like us (due to various limits, etc).

That might be the biggest question.

IF there are, then there have to be, at any given time, some displaced and looking for a new nice place (as we might be someday).

AND IF they are reasonable close to us, and capable of traveling near light speed.

THEN they would be looking for a place just like this.

AND what to do about the pesky existing inhabitants... Well that depends a lot on what you consider the fundamental "nature" of such beings, which may be hard to contemplate.

THEY could mix in, unknown to us.  (Possibly the most likely scenario, I think, maybe therefore already could have already have happened a few times--except that they may not be many such possibilities in the past few million years.  In fact, considering this possibility...it could be that's what "homo sapiens" as we know it now is.  A hybrid of ET's that blended in to establish themselves here.)

THEY could take over, blam.

OR they could try to arrange things, so we did ourselves in, saving them the trouble and cleanup.  But in a fairly benign way.  I don't think they'd like the Nuclear Winter option.  Social collapse from excess growth might be fast enough, once again it's hard to know their fundamental nature.  They could be operating from sone distance mostly, out of view, and not in a huge hurry to take the big prize, knowing they have some time before the next such ET.

So that option would entail giving us just the right knowledge.  Knowing too much of some things and too little of others.

I suppose that point is equally likely even without ET orchestration.
