Namibia sponge fossils are world's first animals: study

Scientists digging in a Namibian national park have uncovered sponge-like fossils they say are the first animals, a discovery that would push the emergence of animal life back millions of years.
The tiny vase-shaped creatures' fossils were found in Namibia's Etosha National Park and other sites around the country in rocks between 760 and 550 million years old, a 10-member team of international researchers said in a paper published in the South African Journal of Science.
That means animals, previously thought to have emerged 600 million to 650 million years ago, actually appeared 100 million to 150 million years before that, the authors said.
It also means the hollow globs -- about the size of a dust speck and covered in holes that allowed fluid to pass in and out of their bodies -- were our ancestors, said co-author Tony Prave, a geologist at the University of St Andrews in Scotland.

I find this doubly fascinating, as it acts both as a furthering of our knowledge of our origins and a tentative confirmation of the 'molecular clock' method of dating.

My Own Religion- An Atheist Creates His Own Religion

My Own Religion- An Atheist Creates His Own Religion

So, if an atheist were to start a religion, what would this religion be like?

This is a question I have been thinking about on and off for some time. Sure, this wouldn't ever really happen, as a religion without a god is not a religion, but it's an interesting thought experiment that I think brings up some valid points and demonstrates how lacking the existing religions really are (not that there are not good ideas contained within; there are). So, what would my religion be like, exactly, if I were to create one?

Let's find out!
