Currently, one of the most accepted theories of the origin of our solar system is this:
1. a "big bang" expansion of protoplasmic phenomena
2. coalescence of this cosmic "soup" into stars after some thousands and millions of years (approximately)
3. supernova star explosions reforming into planetary accretion disks
4. gas giants, rocky planets, and similar moons filling galaxies such as ours
5. abiogenesis upon Gaia
Seeming evidence for this includes:
* the "red shift" of galaxies observed thanks to the Hubble space telescope
* utterly same fossil remains on the east coast of South America and the west coast of Africa indicating "Pangea" existed, all continents, including these, being together at once in the past
* seeing such as below, the apparent remnants of supernova explosions

According to a lecture I saw upon the topic of abiogenesis, approximately 10^55 (a one with fifty-five zeros after it) combinations of chemicals existed on early Earth which yielded, along with the later efforts of those who lived long ago, thousands of types of species and geological actualities that have existed upon Gaia over eons.
