"How is babby formed?"
Thanks be to the man Jesus. Thankee Sai.
With all due respect, it is perfectly clear to anyone not trying to reinterpret the theory to fit the data that it does say that the Earth -- and everything in it -- was created in six days.
It clearly has to be used as a reference point to delineate events. I say clearly because there could not have been a "day" before the earth or sun were created, yes?
