We are JUST RIGHT. If our planet did not spin in a 24 hour rotation it woudl be too clod on one side and too hot on the other. Our temperature drops 10-20 F each night and then another day starts. If our planet was gassy like Jupiter, Neptune, Saturn we woudl al be under a high pressure of gas so high it woudl be like walking on the bottom of the ocean.......
“This is rather as if you imagine a puddle waking up one morning and thinking, 'This is an interesting world I find myself in — an interesting hole I find myself in — fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!' This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, frantically hanging on to the notion that everything's going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.”
― Douglas Adams, The Salmon of Doubt
If the earth was farther away form the sun it woudl be liek mars where it drops to over -100 F. If it were closer to the sun it might be like Venus that gets up to 850 F. We are JUST RIGHT.

If we were not on the outer 1/3 of our galaxy the radiation woudl be TOO HIGH. The center of our galaxy is death ! Too much radiation...
All together there are 68 different things that had to be just right for life. In a book titled "Rare Earth" some scientists speculate we might be the only intelligent life in the entire universe (These men are not Christians liek I am.)
Human beings evolved to fit into the ecological niches left when the dinosaurs became extinct, We evolved to fit into the ecological niches during an ice age because human beings evolved ON Earth , Not on another planet orbiting another star with different surface temperature. I personally believe that BOTH panspermia and life evolving in warm organic tidal pools is how life began on Earth. I have yet to see logical chain of scientific reasoning that explains why EITHER panspermia or self replicating life forms (a virus is self replicating life form) could NOT have evolved life on Earth.
