Evolutionists like to play games, and the play a lot of them. When Darwin first postulate his theory (which really wasn't his), origins was a part of that theory
Have you ever read Origin of Species? In it Darwin is very clear that the origin of the first cell is
NOT part of the theory. This is the relevant passage:
"There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved." C. Darwin, On the Origin of Species, pg 450.
Notice that Darwin is perfectly happy to have God zap the first cell into existence by miracle. Evolution happens
after the first life comes into being.
it wasn't until the Synthetic theory of evolution came around after the official death of darwinism in the 1960's, that origins was taught to be a separate thing from evolution.
WHAT have you been reading? The Modern Synthesis, or neo-Darwinism (what you call the "synthetic theory") was not not the "death of darwinism". Instead, it reinforced Darwinism because it synthesized Mendelian genetics with Darwin's theory:
Synthetic Theory of Evolution
Where did the first cell come from? Until evolutionists can answer this question with confidence (not with unwarranted assumptions that dot the evolutionary landscape like sand on the sea-shore), TOE is out the window.
Because of what Darwin wrote, when people state this, I always know that they are really arguing the atheism vs theism debate, and not arguing about evolution. You are saying that there is a "gap" between non-living matter and living cells. You insert God into that "gap" and say evolution is dead, because you mistakenly think evolution = atheism. Evolution is not atheism. Proof of that is that there are so many
Christian evolutionists here in this forum. Look at my faith icon, for example.
Now, what were the secondary causes God used to create life from non-life? We know of
at least one way for life to arise from non-living chemicals. It's been done. Start with these websites and then you and I can discuss it in more detail:

As you can see, I've done this before.
For a quick summary, when a solution of amino acids are heated (either in a tidal pool under the sun or at a hydrothermal vent), they polymerize to form proteins. The proteins, in turn, spontaneously form cells. These cells have the 4 characteristics that, together, define something as alive:
1. Metabolism (both breaking down chemicals for energy and building up larger chemicals from simpler building blocks).
2. Growth
3. Response to stimuli
4. Reproduction.
God created the first cell by chemistry, not miracle.
