Terraforming the Terra by Wes Penre. Enki Lord of Earth.

WES PENRE PAPERS: After he had eventually rebuilt the atmosphere and the magnetic field, ENKI let Founders from
near and far direct asteroids and comets towards Terra, asteroids which included specific DNA that would help recreating the life forms on the planet, and for a while the atmosphere was bombarded with space rocks. ENKI selected a team of scientists and they settled down in an area of the planet that is today the eastern part of Siberia and started building laboratories high up on a mountain, where the earth met the sky, where there was a big lake. Here was where intelligent life was going to be seeded once the reconstruction of Terra allowed it. by Wes Penre, 2 Level of Learning, p.196.
