You're playing word games and/or creating strawman arguments,
methinks, Tom.  I'd guess everyone agrees that the sun was an
energy source on the earth.  Call it what you will, but at point in
time T, there was no life; while at point in time T', there was life.
Call it "forced", call it "emerged", call it
"materialized", call it
"arose", call it "came into being" - life
"began" between times T
and T'.  The factors involved were likely manifold, but I doubt
*anyone* thinks that life "emerged out of nothing", and there is,
therefore, no important difference here.

What all the factors were that played a part, no one knows, but
appropriate levels of sunshine (most or all frequencies) was likely
a major one, as likely was the existence of organic compounds.
The existence of water was likely a third major factor.  Volcanism
also may have played a part.  Location within the galaxy may have
been a factor as well.  And luck, chance, fluke, etc., likely played
a part, too, whether for the initial appearance of life or for its
continued existence (e.g. had a Permian/KT-style event taken
place in the first few million years of likely tenuous life, it could
have been wiped out completely - just a guess).

My issues with the (fairly popular) "chemical replication, then life"
scenario is that both replication and initial life are pretty unique
items, I think.  To have (very rare) *life* piggyback on (rare)
*replication* seems to worsen the odds of life's emergence
phenomenally.  That is, not only do these rare items - independent
replication and life - have to happen, but occurrences of them have
to actually intersect appropriately in both time and space).

If life is to "emerge" anyway (but *not* "out of
nothing"), lets let a
simple life-form do the replicating and not make the odds so much against
it.  All that being said, I confess that my argument is mainly based on gut
feel and thinking of the odds and not much more.  Regards, Brett.

P.S.  Personally, I like any of my terms in Para. 1 more than "forced".
