i live my life by Christian values.

I belive in christianity but theres some parts i question.

such as someone said, if man was put on the earth in 7 days from when earth was created, how did we evolve from a tiny grain of sand size organism to what we are today in 7 days.

how did the dinosaurs rule the earth 10 000 000 000 years ago if the world - man creation was only 6 days. LOL
