The evolution of life on Earth is/was dependent on the evolution of the Earth itself. We know several global extinction events have happened in Earth’s past. These events are all unique to Earth and the life that was on Earth at the times of those events evolved uniquely because of those events. Also, just because physics seems to have rules, most of which we don’t really understand fully, doesn’t necessarily mean those same physics apply to all areas of the universe. We assume physics is the same everywhere but we don’t really know for sure. Life may be very common but to think it’s similar to the life that evolved on Earth isn’t a fair comparison or assumption. We don’t really know.
