There is no god. Even if there were, it clearly doesn’t give a damn about you missing some bodily tissue. If it did, it could fix it! How do we know this? Science!

The fabulous website whywontgodhealamputees.com is based on the challenge that if a god is all-powerful, all-loving, and promises to answer prayer, then why won’t this god heal someone who has a missing limb? It’s never happened, and we know it never will. At least, not through prayer.

An exciting landmark has been reached in regards to a gene that may regulate tissue regeneration in mammals (that means humans too, Creationists!). This ability to replace damaged flesh with healthy, scar-free flesh seems to be triggered by the loss of the p21 gene. When the p21 gene is lacking, cells behave more like embryonic stem cells rather than adult cells.

“Much like a newt that has lost a limb, these mice will replace missing or damaged tissue with healthy tissue that lacks any sign of scarring,” said the project’s lead scientist Ellen Heber-Katz, Ph.D., a professor in Wistar’s Molecular and Cellular Oncogenesis program. “While we are just beginning to understand the repercussions of these findings, perhaps, one day we’ll be able to accelerate healing in humans by temporarily inactivating the p21 gene.”

[Andrew Snyder, Ph.D. stated,] “In normal cells, p21 acts like a brake to block cell cycle progression in the event of DNA damage, preventing the cells from dividing and potentially becoming cancerous,” Heber-Katz said. “In these mice without p21, we do see the expected increase in DNA damage, but surprisingly no increase in cancer has been reported.”

If it may work on a mouse, could tissue regeneration be available to humans in the future? Do you think this would encourage or stifle the superstitions about divine healing?
