The odds of an average size protein such as hemoglobin, assuming all the required amino acids with the correct chirality, are 10e630. All the atomic particles in the universe are 10e89 and time is 10e27 nanoseconds. That is just one thing the evolutionary miracle will need to overcome. By the way the smallest chromosome in the human body has 1 million amino acids in it. Put that together using random chance.
Life didn’t begin with hemoglobin. Simple became complex. If it happened here it can happen anywhere.
“By the way the smallest chromosome in the human body has 1 million amino acids in it.”
Are you saying that chromosomes are made up of amino acids or are you talking about the proteins associated with chromosomes?
