I asked this question before but people got confused. Evolution works on the principle of abiogenesis -- and scientists say that life on earth started when molecules randomly came together to make a living cell.
Well, why can't we replicate this in a lab? Nobody has managed to get a beaker of material which resembled primordial Earth, and observe a living cell being made randomly from the unliving molecules.
I'm not talking about amino acids -- I mean a whole living cell, coming together through chance in an experiment. It HASN'T happened.
And don't say test-tube babies are an answer, because that's using sperm and eggs from people, and using something supposedly already evolved to make life.
Why hasn't it happened?
