answer:This is a tough bunch of questions since even my own opinion keeps changing on some of them. I have no idea how the universe was formed, although the Big Bang and its supporting evidence make the most sense to me. How was the Earth and other planets formed? I think it’s pretty common to believe that large bodies of matter were brought together from clouds of dust and gas left over from the formation of stars or other stellar events. Life? Sure. When the universe is so large with so many galaxies, star systems, and planets (more are being discovered each day) I find it extremely difficult to believe that we are the only form on life anywhere… Finally, it’s my opinion that there are alternate universes, because my feeble mind can only accept certain scientific theories when more than one universe exists. Whew.
