The Earth and its solar system do not look like anything near resemblance to an African jungle of primordial DNA life variants creation. We should see more distinct DNA variants, maybe see them re-appearing all the time around. A huge evolutionary gap on Earth in the DNA creation area that we are stil, relatively, quite superficially finding local reason for. Given the little found evidence for Earth being able to be a flourishing creative place for DNA life code with multiple distinct variants, we may more likely assume for primordial life on Earth being seeded from somewhere else.
The fastest and strongest life development places are also generally likely to be more of reasonably stable, habitable space jungles, creative edge borderline places. By comparison Earth looks like a very nice cool place. Evolution on Earth was very slow, and by now we could be quite confident that it could have been well faster in a more dynamic and pressing place that is still richly habitable. Considering the likely patterns of creative possibilities the Solar System and Earth feel like a seeded garden, a place to slowly develop something nice, something of highly reliable, slowly developed, good balance high quality.
