    meteorites are made of the element that we call" Iron "in the table of elements.

    See the Biblical record of Creation how biological life source came from.

    once earth maintained a steady orbit around its sun, Meteorites may contain elements that give off heat, thus allowing life to form near by when there is night and day.

    No, "The God who made the world and everything in it is the Lord of heaven and earth."

    Depends on your definition of "origin"... It's been found that comets contain amino acids - not life itself, but the *beginnings* of life - and that they could have brought those building blocks to Earth. It's *possible*, but not proven.

    Not likely. Conditions needed for life to begin needed to be stable for millions of years. Meteorites never have stable conditions for anywhere close to that length of time.

    No one can answer that question with certainty.

    My personal view is that the "not from earth" origin theories are a bit of a dodge, because they don't actually answer the question (how did life get started), they just push it off to another place. The question is still applicable: how did life start, no matter where you want to put it when it started. It matters a bit because it means we can think of the conditions for origin of life as being different from what earth could have ever experienced, but it does not much answer the actual and important question of how did it come to be in the very first place.

    Sort of like saying God made the universe, we have just displaced the question to what made god then.

    No, but they are carriers.

    Meteors and comets brought the chemicals that led to life such as amino acids, and some nucleotides if I remember right. The oceans were basically a giant chemistry experiment driven by heat, UV radiation, and lightning that eventually led to just the right combination of molecules that a molecule was formed that could make crude copies of itself. That eventually led to the first cells that we could define as life.

    There is another hypothesis that Mars had life on it billions of years ago, and meteors that hit it ejected rocks out into space that had microbes living in the tiny cracks inside it. Over time some of those rocks made it to Earth with some of those microbes that were hardy enough to survive the trip, which found a hospitable place in the oceans where their rocky space transports landed. The hypothetical idea is called "panspermia" and will remain a hypothesis until and unless we find current life or evidence of past life on Mars.

    Indirectly they were. Asteroids brought water when Earth was being formed. Life originated in the Oceans.

    That speculation is common - but there is little evidence to support it.
