A number of secular cosmologists claim that our universe is just one of many universes that exist. Why do they say this? Is there any evidence for this claim? And how does this relate to the creation-evolution controversy?

Secular scientists use the Milankovitch theory to explain the 50 or so ice ages they believe occurred in the last few million years. According to this theory, slow changes in Earth’s orbital and rotational motions change the amount of sunlight falling on the northern high latitudes during the summer months. Supposedly, ice ages result when this summer sunlight is at a minimum.
