Biblical Creationism Requires Evolution

Yes we do, through the sciences of Genomics and Systematics.

Of course, all of science is tentative, so Genomics and Systematics are, at the core of it, tentative sciences. However, their conclusions and predictions are so accurate the vast majority of the time, that we can build genetic infrastructures on top of them.Genomics is the study of the genome, which is the study of DNA, which, through scientific methods, can give scientists accurate insights into the relatedness of species and individuals.Systematics is a branch of Genomics that deals specifically with species interrelatedness.

Yes, science, by its definition and by its methods, unless the science happens to be mathematics, will not every conclusively say anything about anything.But that doesn't change the fact that using the information we get from Genomics, we can make countless working medicines, diagnose countless diseases and clone many organisms, accurately, predictably and safely.
