We are still in the speculation phase on how life got started. The one thing we are sure of it that is would have started very primitively, possibly based on PNA, then graduated to RNA (Ribonucleic acid) then to DNA (Deoxyribonucleic Acid). A fully formed amoeba would not just have popped into existence. I hazard that when we do understand, will be very hard to decide where in the painfully slow evolutionary process life actually started. The earliest lifeforms will look very unimpressive, hardly worthy of a deity’s attention, more like eccentric organic molecules.
