Yes, the earth’s creatures have evolved through a series of contingent and fortuitous events. 

1. Our earth is just the right distance from the sun to have a stable orbit. Our orbit keeps us from getting too hot or too cold to survive. Any closer we’d burn up, any farther away we’d freeze to death. 

2. Our earth is perfect in both size and mass. Mass is critically important to the formation of an atmosphere. If the earth’s mass were less dense, an atmosphere could not have formed and remained. If it were more dense, the atmosphere would have been uninhabitable. 

3. Our earth has just the right mix of the 27 elements needed for life, including carbon, oxygen, nitrogen, phosphorous, potassium, iron, sodium, and copper. 

4. Our earth has just right amount of water in the proper ratios of liquid, solid, and gas.

A little more and the continents would probably be totally overrun with water and literally, drown.

Any less and the temperature of the earth would probably be too hot making life unbearable here. 

Thus we can say that our being on this earth is the result of fortuitous accidents.
