It is astounding how many egregious errors you packed into a single sentence and the irrelevant diagram.
First, the sentence:
- As others have pointed out this cell is not representative of the first cellular life. More on that later.
- The phrase "supposedly appears" implies sponataneous or very rapid emergence of the first cell. I do not know of amy practicing biologist, or biochemist, who thinks that was the case. If you did not mean to imply that please choose your wording more carefully in future.
- No puddles were involved, unless you think of the oceans, tidal pools and waters surrounding thermal vents as all subsets of the puddle class.
- Toxicity is specific to the organism. There are many species of bacteria today that thrive on what to us are excessively toxic conditions. Those bacteria happily gobble up those "toxins". Curiously these generally seem, along with other extremophiles, to be the most ancient forms of life still extant.
Then the diagram! The first cells did not contain:
A nucleus
A Golgi vesicle
An endoplasmic reticulum (smooth, or soft)
Mitochondria
Any other organelles as complex as the eukaryote cell you have shown
In simple terms you have shown a diagram of a B1-stealth bomber and asked how the Wright brothers could possibly have built that at a first attempt.
As other have suggested, if you wish to have your posts taken seriously then please don't post such error laden material. It offers no opportunity for discussion, only correction of the errors.
