So life began because different molecules were randomly mixed together, which caused certain reactions to take place,,,,,.
Randomly? Your words, not mine.
Do you consider that to be a rebuttal?
To an assertion as poorly supported as the one you provided ("it just has
to be a result of intelligence!"), mocking laughter would have been an adequate rebuttal. Can you provide a single known example of intelligence that hasn't arisen as a result of natural processes, for which you can provide a shred of reliable evidence?
You actually believe the spontaneous generation nonsense?
Abiogenesis is not spontaneous generation. Spontaneous generation was an old notion that stated that complex organisms were "spontaneously generated" from decaying ones. It has long since been discarded, and we now know it to be false. Abiogenesis, on the other hand, says no such thing: rather, it says that primordial
self-replicating systems arose at some point in the distant past, and most likely under very different Terrestrial conditions to the ones that prevail today, from simpler molecules and compounds. It is a current scientific hypothesis - one with some degree of support, and in which field research is ongoing. I would say that I am reasonably confident that it will eventually produce further positive results.
Perhaps you are unaware of the complexity of cell biology. Darwin, certainly, was unaware of the complexity of a single cell.
I am dimly aware of the complexity of cell biology (though I would not claim to be particularly knowledgeable about it, as I am not active in the field). There is, however, nothing that says that primordial self-replicating systems had
to be anywhere near as complex as a modern cell.
What makes the genetic code a "language" is the fact that DNA stores information, retrieves information, and uses information to build a creature...
...In other words a creature is built according to a very precise set of instructions...
Precise, that is, save for the various copying errors, and to make note of a small point, modern DNA couldn't do it without the assistance of the apparatus of that complex modern cell you mentioned - and even then, nothing useful would come of it but for the steady supply and appropriate balance of nutrients from the immediate external environment (e.g. the mother in placental mammals).
But what makes the various codes in DNA "information"? Again, I would put it to you, it is the process of natural selection that provides that differentiation between various types of organisms.
...starting with a single cell (egg) and sperm.
... which has been stored in the single celled egg and sperm.
Egg and sperm? Only in sexual reproduction.
What is the origin of the instructions?
In sexual reproduction? The parents, obviously. In asexual reproduction? The parent, obviously.
