What might comets and/or meteors have had that might have "seeded" life in the oceans?
It has been scientifically proven that life in the oceans might have been seeded by comets or meteors since they bodily masses were in existence before the formation of earth and they carried many things within their form. In addition, comets exhibit a very high speed, which has the potential of causing destruction, on like in this case, the ability to make life on the planet. The seeding of life in the oceans as related to the comets makes a perfect sense considering a theory where the comets hit the earth’s surface (Erickson, and Timothy 32). Indeed, an empirical research has had a major breakthrough where these comets have been discovered to have amino acids molecules, and this gives a great idea about the creation of life on earth. The concept of creation of life is held by a common phenomenon that Amino Acids contained in these comets or meteorites crashed on the earth’s surface thus scattering life-giving contents. These components combined with water derived from impacting planetoids also contributed to the formation of earth.
What had to happen on Earth before life could move out of the oceans (the crust of the Earth had long since have cooled off). (Hint it had to do with the conversion of the atmosphere due to photosynthesis.)
Before life could move to the earth from the ocean, the earth was devoid of anything, and the earth had to undergo systemic transformation in order to support various life forms. In the advent before the existence of life, the emergence of photosynthetic organisms was key to the formation of earth. Examples of these organisms include blue-green algae, which existed in the ocean way before the formation of life earth. These organisms fed on atmospheric carbon dioxide, which led to their conversion into marine sediments comprising of shells of sea. A fundamental biological process known as photosynthesis had to occur before the formation of life (Erickson, and Timothy 42). This process reduced carbon dioxide content of the atmosphere as so the production of oxygen began. The formation of oxygen was not realizable since most of them were absorbed by rocks. The photosynthetic process led to the advancement and formation of oxygen, which would become essential on earth.
