I'm maybe the only one who don't believe the great Bing Bang has created the universe and planets.
For my thought, universe and planets are always exist. There is no beginning and no ends.
Planets can born and die but they are always there in the universe.
The only reason people believe the universe and planets were created by a bing bang, they are obsessed there is a beginning of the creation, scientists choose the Bing Bang instead god or gods (according to religions).
When you read these lines, other Bing Bangs occur somewhere in the universe.
For me, Bing Bang is something else.
