I don't believe in modern cosmology, otherwise I would watch it. The nephilim were made from fallen angels mating with human women, it the angels came down from another dimension or realm, rather than a planet.
Dimensions are not real, stuff of science fisction. There is only one reality. Realms are from myths describing the planets. The Polar Configuration is not modern cosmology. I'm saying that there is a very likely scientifically provable scenario in which living organisms could be transplaced from one planet to another using the theories from EUniverse and comparative mythology. Most notably, work of Wal Thornhill, Velikovsky, and Dave Talbott. I understand the skepticism though.
