Nevertheless, many scientists became convinced that, under certain conditions, a living cell can arise from nonliving molecules. However, this view only became popular because scientists believed (incorrectly) that living cells were relatively simple structures (little blobs of protoplasm). The following video shows how unimaginably mistaken this assumption was:
Of course, most biologists continue to believe that life arose from non-life. But this simply shows how reluctant people are to give up established theories (even when those theories only became established because of false assumptions).
