Indeed. The joke was the premise of wanting to explore the history of the theories.
We are exploring them, tacticalogic. Just not so uncritically as you'd prefer. Are scientists not human, subject to the same vagaries of pride and predjudice, as the rest of humanity? I see it writ large, in a self-serving, centuries long effort to contravene anything remotely supportive of Biblical history. You see it as an unbiased process, in search of "truth where ever it leads." It's certainly led a wide swath away from certain potential truths, though. That's bias.
