Nebulae have been observed both within the [[Milky Way]] [[galaxy]] and in other galaxies. These large clouds of mostly hydrogen gas can form stars and planets. Secular scientists believe our solar system formed about 4.6 billion years ago from a nebula. <ref>http://www.windows.ucar.edu/tour/our_solar_system/formation.html</ref> |
