Don't you think it should have been a low proberbility that it was able to even sustain it self for a lifetime? Isn?t it an even lesser proberbility that it reproduced itself? Was this achieved after millions of attempts - the sustenance? Did it take billions of attempts to achieve reproduction? Why is reproduction so difficult in fully developed humans in some nations today?

You have to remember that proteins are not goal-directed.  Evolution does not plan to make insulin.  Rather, insulin could have been made by chance.  Since there are so many proteins in the cell, a protein that served a function could have come up at random.  It did take billions of years, and the first cells were not very complex.  Still, it was an amazing achievement, almost unbelieveable.  Even a single protein.  There are two theories circulating on how organic molecules were made before enzymes.  Either hydrothermal vents with static charges used their energy to synthesize Notrogens, Oxygens, Carbons, and hydrogens together to form an amino acid which were synthesized to make a protein, or it came on a comet.  A meteor that hit earth did have some organic molecules.  The proteins couldn't die, since they were never really alive.  Could the first cell die?  Well, the first cell probably did die, and very rapidly, since it could not sustain itself.  But it's hard to define a point where the first cell was alive.

mose it is like your not stand there you are a time traveler like the rest of us and education was only a trace element of the real truth. the longer you look at the things we know the harder it is to remember how far we've come~sun has come and gone so many times in history that the Edgar Cayce style of overview show that ice is hold secrets now that the sun is still thawing out now, as we endure global warming we are instilling life into overlapping ideologies in time warp that occur in instantaneous freezing of ice age things that we know nothing of is slowly drifting on the warm side of the underneath of glaciers embedded with crustaceans of reentering forms of struggles to live by elements that are invisible or even not interpretable in real time as we lack where they were one hundred and eighty million years ago,poverty,stress,greed is the answer to your last sentence
