What do you think "transubstantiation" means? What does the doctrine teach us about the observable aspects (i.e. the apearances) of the communion elements?

It teaches us that there are a lot of doctrines in the Catholic Church that are just... not... biblical.
I do find it interesting that so many Catholics are willing to accept the accidents and appearances as fact in regard to the communion, but when it comes to believing that the Earth was created in 6 days, they scoff at the creationist "whackjobs" who actually believe that "despite all appearances to the contrary" that God really did create the heavens and the earth in 6 days.
On the one hand they deny all natural observations to the contrary and insist that what they are consuming is the "literal" flesh and blood of Jesus Christ, yet they scoff at anyone who takes Genesis literally and actually believes that the earth is much younger than it appears.
If "accidents and appearances" can explain the eucharist, then why can't it explain the creation?
