Meteorites play a role in ideas about how life on Earth began.
Here are three examples.
1. Panspermia is the theory that life exists throughout the Universe is transported by meteoroids, asteroids and planetoids from one region or galaxy to another.
2. The exogenesis theory is a more modest and conjectures that life on Earth was transferred from elsewhere, possibly via meteorite.
3. In 1996 a meteorite, ALH 84001, was conjectured to show fossil evidence of life on Mars. The meteorite was found on Earth after being knocked off Mars millions of years ago.
None of these theories or conjectures have been proven correct or even strongly possible. None have been proven wrong either.

Is there another planet in outer space that's just like earth?
In life-wise terms, no.
How can a cosmic impact affect life on the earth?
A cosmic impact is an explosion that occurs in space when two objects collide. It is quite possible that asteroids and other debris in outer space would collide with each other from time to time.
How do comets affect life on earth?
Exobiology speculates that microscopic life originated elsewhere and was brought here by a meteorite sent off by some violent distaster, which while it has not been proven is very scientifically plausible, as germs and viruses have proven to be able to survive in outer space and there is a gigantic gash on mars (a planet with water likely to have once supported life) which could have sent such a meteorite into outer space. Also, since comets are thought to be made substantially of water ice, it is theorized that they are the primary source of earth's water. It may seem unlikely, but in the early stages of earth's development there were probably many, many more comets than there are today, and it is not impossible that enough comets could have collided with earth over millions of years to supply us with our water.
Did mushrooms originally come to earth on a meteor?
It is an interesting idea that life may have come from other parts of the Universe, but there is no evidence that this really is so (nor that it isn't, for that matter). Also, specifically in the case of mushrooms, despite all their differences, they are probably too similar to other life on Earth to have evolved independently from it. If life did come from outer space, it may have been a common ancestor to ALL current life on Earth.
How can an orbit of a planet affect life on that planet?
The only planet in that category is the Earth, the planet most people live on. How does the orbit affect life? without the orbit there is no life on Earth, so it's fundamental really. The orbit keeps our temperature within narrow band so that life can exist and flourish. Without an orbit the Earth would travel off into outer space and the temperature would quickly descend below -200 degrees everywhere.
Is there another planet in outer space that's just like earth?
In life-wise terms, no.
Has life been found yet in outer space?
No, so far we have found no life in outer space. Life may well exist in outer space, but we haven't found it yet.
What do astronauts do in outer space?
They study how long to get to planets and if there is life in outer space.
Study of life in outer space is known as?
Astronomy is the study of heavenly bodies.
What would happen if you took LSD and went to outer space?
You would most likely have the best acid trip of your life. Looking at the earth from outer space would probably bring you a sense of how small you are compared to the earth and how short life really is. Im sure it would be life changing and make you a more humble person :)
Is outer space closer than deep space?
i honestly don't know if this is correct or not but i am pretty sure that outer space is space as a whole. they just called it outer because it surrounds the earth and goes around our spheres. deep space is further out in space. this is where most of the scientist go or want to go to find life or other interesting discoveries.
What is the mission of the spce probe in the outer space?
The mission of the space probe in outer space is to find out information about regions that are too far to see with telescopes. The space probe looks for life on other planets and weather conditions, asteroids, and other things that can affect the earth.
Will people on earth ever find intelligent life in outer space?
maybe, well i heard there was life on mars...just maybe sorry idk no either
What is panspermia?
It is the hypothesis that life on Earth originated from microorganisms from outer space.
How can a cosmic impact affect life on the earth?
A cosmic impact is an explosion that occurs in space when two objects collide. It is quite possible that asteroids and other debris in outer space would collide with each other from time to time.
What is the study of life in your outer space called?
Exobiology.
What is the the main energy source for life on earth?
Sunlight is the main energy source for life on earth.
