What if religions are wrong. We were from somewhere else or we were here before we thought we know the beginning.

one of the evidences is crystal skulls
"From Anna, Ceri and Chris learned that in the late 1970’s leading scientists from Hewlett-Packard crystal laboratories in Santa Clara, California had carried out extensive tests on the skull. Polarized light tests showed the massive cranium was made from just one piece of crystal and the jawbone was carved from the same piece of rock. The scientists said the workmanship on the skull was such that it would be almost impossible to reproduce, even with the most advanced of modern tools."

if so, we might be the alien of the planet. and who are our ancestors?
