Self-arranging and self replication are actually easy enough to do that
the old definition of life that depends on that have been discarded for

As an example, lipids, or phospholipids, are a common substance (read
oils) that have the tendency to form into small bilayer spheres that
isolate the interior from the exterior world. Then what is needed is for
the right compounds to get trapped inside that sphere, and maybe
something interesting will happen.

Point is, these things are not some impossible to happen, "just so"
scheme. As time goes on, it looks more and more like on a planet capable
of sustaining life, life will happen.

Now if someone wanted to claim that some entity made that planet that
could support life, then these things happened - that is a different story.

I'd say that was the best argument for aliens I have ever seen ...

Since the universe is some ~13.7 billion years old, and the earth only
~6 billion ... it would be quite interesting to meet one of those races
who are ~1 billion years ahead of us ... I am waiting, indeed, have been
for some time now.
