It is widely believed by evolutionary biologists and scientists that
we all came from that first life form that self-replicated long ago.
However, it always seemed more logical to me that separate life forms
appeared spontaneously around the same time in different parts of the
"primordial soup". From there, different species took off and
evolution ran its course from perhaps several different beginning
simple life forms. Is there evidence out there that we all came from
this single initial single-celled organism that self-replicated?

As a biologist, I can't say I really agree with your characterization
that scientists generally believe that "we all came from that first
life form that self-replicated long ago..."

Your notion that a viable living organism might have spontaneously
arisen on more than one occasion is plausible.  I don't know of any
scientists who argue that it absolutely happened once, and only once.

Bottom line is that we really know very little about the actual steps
whereby inorganic matter gave rise to living organisms, so all
possibilities are on the table, I would say.

Just my two cents...

There is no answer at this time.

You are referring to Luca (Last Universal Common Ancestor), the thing
is, Luca didn't just appeared out of nowhere, in it's world there
could've been thousands or tens of thousands of other like structures.
They would all interact with each other and eventually (just like
paternal lines in humans today) all the others got eliminated or
incorporated into what today we think of as LUCA.

Just google:

evolutionists like to believe that we all came from a single ancestor
cell because of the universality of the dna code, they say that since
all living posess the same 4 letter code for life (A T G C), it means
that we came from the same cell.

if they admit that not all the living came from a single cell they
must admit that, by chance, multiple living celles at different places
around the globe created the same exact 4 letter code in their dna,
they do not like this because this theory would support more the
"common designer" more that the "common ancestor", in other words help
the inteligent design theory which is in direct contradiction of their
beliefs in evolution
