  • @dave6001 Anytime you use the word prove, you have just ruined you're entire argument. Nothing is proven in science. It is only supported by evidence until either an alternative explanation is brought or until no more alternative is brought, but it is never proven. @FascistBros There is not one single species on the face of the Earth that cannot be explained by Creationism, but that does not necessarily make the explanation accurate.

  • @nefz117 its a question of right and wrong, evolution is right and has been proven right

  • brilliant video

  • good work here

  • Like.. if you are from SMU

  • @Dragan572 sorry i said RNA protein I meant just RNA

  • @bigdad4554 Actually RNA came before DNA and protein, which stops this chicken and egg problem. The concept is called the RNA World. Not all enzymes are proteins, ribozyme is a RNA protein that allowed RNA to replicate itself and form peptide links in protein. So the prokaryotes that existed, has the ability to from tRNA, mRNA and rRNA all from this enzyme. Eventually, DNA is used because it is more stable due to the remove of the 2'hyroxyl group so that it is inert and carries info.

  • Which came first? The Protein that the DNA constructs or the Protein from which the DNA is constructed?

  • @nefz117 but isn't it funny that there is not one single species on the face of the earth that cannot be explained by evolution. Not a single one. You would have thought that an intelligent creator would have created something through ONLY intelligent design to show his presence?

  • Snowflakes are designed by the creator and and so is the programmed super complicated DNA.
