Assuming you mean "different" life forms, it could be one of two things depending on your beliefs.

1. God made everything in 7 days.

2. Life developed from single celled organisms which evolved into more complex organisms which evolved into even more complex organisms...so on and so on over a period of 3.5-4 billion years.
