Darwinists maintain that there was no oxygen in the period when life emerged, and that oxygen formed subsequently. Because the existence of oxygen will entirely repudiate all their claims about the beginning of life. Darwinists know that when an amino acid forms in the primeval atmosphere, in the way they maintain, oxygen will immediately burn it up and destroy it. For that reason, they are unable to use oxygen in experiments concerning the origin of life. And all experiments conducted without oxygen have failed. The famous Stanly Miller conducted his experiment in an oxygen-free environment, and he subsequently had to admit that his conditions did not match those of the real atmosphere.
