Argument for Non-Life to Life on earth?

Question

Has anyone ever thought that maybe the key to life starting on earth really didn't start from earth. Since they found bacterial life on mars maybe since the earth back a million years ago was being hit with all kinds of space debris it brought bacteria or other forms of life from other parts of the universe and thats where the life came from....I mean we see other galaxies being formed all the time so maybe conditions were just right to start life then evolution? Who knows what was going on at other parts of the universe...but maybe thats the jump start the it needed. Life didn't just form on earth but it was brought here? Anyone else think its possible? *Religious people...please spare the bible verses and the rantings...I think this theory makes more sense.

Lana How can you say that Nasa made that up...yet im sure you can't even comprehend that as time has went buy religious people have made things up too?? how do you know Jesus's friends didn't make stuff up about him? You can so easy say that nasa is lying....but you probably think the bible is pure fact....People's Ignorance Amazes me!

Answer 1

Anyone who hasn't considered this as a theory to how DNA first appeared on our tiny planet in a vast galaxy is an idiot. I'm not saying it's the correct theory, but it is a theory and people should be prepared to learn and glean knowledge from the wonderful information we have available to us now, that people didn't have for thousands of years.

Answer 2

The process of life going from one object to another on meteoroids or comets is called panspermia, and there are many prominent scientifists who think it happens a lot. Personally I think life probably arises fairly commonly in the Universe, judging from what happened here on Earth, but I'm not so sure that panspermia is a common event.

However, one thing I can tell you for sure is that people have not yet discovered any bacteria on Mars.

Answer 3

100%. It happened. And, by the way: "Atheists typically hold that a belief in god requires turning a blind eye to all facts, science and reason, but what are the odds of life originating from non life, as calculated by scientists themselves?" NO. You are an ignorant person. An atheist says, that due to your LACK OF PROOF of the EXISTENCE OF GOD the default position is NON EXISTENCE. Being an atheist has NOTHING TO DO with evolution, the creation of life, sports scores, the start of the universe, or how many vibrators one has in their drawer. And only an IGNORANT MORON would not know that. A FINAL THOUGHT ON YOUR REFERENCE: Coppedge, James, F. 1973. Evolution: Possible or impossible? is the same: James Fletcher Coppedge, founder of the Rangers and Christian Commandos and the Valley Cathedral Youth Center. Not a reliable source on Evolution.

Answer 4

a good question, the possibility of life in other planets, basic forms or advance forms its huge, we dont know how big is the universe and his time, we are only a fragment or a second, we know life forms advace life forms like dinossaurs lived in our planet before we did a planet with the same conditions or even worst conditions can stand other type of beeings, its evolution that made who we are, but who realy built all this who was the arquitec, are we an accident? probably

Answer 5

Well, it has to have started somewhere, right? And if it can start once, what's to say it can't start again in a similar fashion somewhere else?

Anyway, it makes since. Life, evolution, etc. is all built on a simple premise: If something is better at making more of itself, there will be more of it. thus, make since that something that gains the ability to reproduce will spread. Hence, life.

Answer 6

I don't think it has been proven that bacteria have lived on Mars.

In my opinion, although it is possible life could have been transmitted to earth, it only pushes the problem further away: where did that life come from.

I think the early earth had sufficient environmental resources to develope the first replicating molecules.

Answer 7

Possible. Who knows. Interesting theory.

Answer 8

I think you're wrong callmetamu, i wouldn't be surprised if bacterial spores or like could survive space and re-entry deep inside of a meteorite/comet etc..

Answer 9

It's certainly been thought of. Look up panspermia. Of course, it doesn't answer the question of how life began, just shifts the origin.

Answer 10

It's impossible: re-entry would cause any bacteria to burn up in the atmosphere, not to mention they would be unlikely to survive the radiation in outer space (and of course you might have issues with it being too COLD).
