      IIRC; Tilted axis gives us the seasons by doing so causing weather and water streams. Also lightning. Having a moon causing the tides is what’s believed to be the reason for the chemicals in the dirt and rocks mixing well to prepare the amino acids or something similar.

        Having a moon causing the tides

        Our moon is not the only reason for the tides existing, our Sun kinda also have gravity, so it causes tides too.

          The moon, due to it’s unusual size and proximity for a moon, has a much greater effect on the tides than the sun. That’s why the tides are more closely linked to the moon’s orbit around the earth, not the Earth’s around the sun.

            They are linked to both though. That is why you get even higher tides at some times of the year. The moon has a larger effect but they can combine.

      There are a few reasons but I kind of think it boils down to biodiversity. Seasonal changes, tides, light exposure, and varying temperatures would affect the balance of diverse life.

      For example, Earth didn’t always have oxygen. 2.4 billion years ago there was a bunch of microbial photosynthesis happening. Seasons and the tides affect ocean currents which moved nutrients around, allowing the bacteria to thrive and grow.

      Ozone’s formula is O3, so the Ozone layer wouldn’t have formed either.

      There are also other issues like how the seasons affect biological migration or how the moon slows the Earth’s rotation to about 24 hours/day.

      Seasons add variability, which helps select life that is adaptable and less likely to be wiped out.

      Moon keeps the ocean moving, circulating the oxygen and nutrients.
