Panspermia Theory suggests that life seeds came from outer space and planets exchanged life. Panspermia literally means seeds everywhere.
Panspermia suggests that life could have existed on another planet and moved to Earth. Statistics have showed 7.5% of rocks from Mars reach Earth. The rocks would travel between less than 100 years to 16,000 years and more to get to earth.
Some of the proponents include Sales Gyon de Montlivant, who proposed life came from moon, H.E. Richter, who suggested life came from meteorites/comets, and Svante Arrhenius, who came up with Panspermia.
I find this theory very interesting, so I would love to hear your opinions on this.
Life seeds as in actual seeds that make trees? It has slight evidence that suggests so, it just needs more to have a certain amount of merit. So...these meteors, which bear the seeds from other planets, would travel to earth, hit it, and have the seeds blown off and reach fertile soil. The only planet that's possible to have this happen is Mars, since there were tests that suggested that there could have been life before. Then the rocks would travel to earth, hit it, bear the seeds, etc. etc.
It's a nice theory, I'll give it that. It just needs more evidence to back it up. The theory about the moon is outta whack though.
Sounds like BS, any lifeform advanced enough to get to earth whould be able to prove it, and the rocks themselves can't make it past our atmashpere, thus anything on it whould shurly die.

Depends on the size of the rock... Meteorites big enough can cause mass destruction... such as the one that supposedly whiped out the dinosaurs.

Sure they can! They have before. Seeds are always embedded in soil and could surely survive. Also remember that pre-Earth had a weak atmosphere at the time and needed more gas to power it, so to speak. Meteorites could definitely make it, given the amount of size.
But, I'm just having an open mind right now. I like it so far.

Rocks smaller then your fist, that are hot enough to melt steal...
Yes they could have made it, but it whould have to be a plant that evolved specifically to go to another planet. It whould have to burrow maney feet into solid rock and be able to withstand extream heat and extream cold, and it whould not need food, watter, or oxogen (carbon dioxide in the case of plants of course) for long periods at a time, be able to predict what rocks will fly off, be able to withstand the crash, be lucky enough to land on the small part of earth that was land, and finally be able to get to firtile ground.

1. plant seeds do not need to know if they are going to travel to another planet. That's just silly
2. Weakened atmosphere = MUCH less pressure. As in large rocks were like golf balls compared to the larger scheme.
3. Lots and lots of carbon dioxide in pre-earth. this is the plant's life supply, as oxygen is to us. They take all that and expend oxygen, which again how life really took a dive forward.
4. Plants do not and cannot predict if their land is going to take off. Either they are in space or they aren't. Plant seeds do not have brains or an intelligence for that matter.

Exactly, thats one of the reasons its extreamly unlikly.

Yes but Earths gravity still whould cause them to accelerate and heat up, and the vaccume of space causing them to freeze.

But once again, not in space.

Once again, exactly. They whould need to know were to go to go to earth, be built to make it thier, and to know how to, whitch is why I find it extreamly unlikly...
It refers to simple single celled life. However I still find it unlikely. A space born organism would have about as much trouble surviving on Earth as we would on Venus with no life support. If your saying the organism came from another planet this becomes even less likely. Because not only would it have to survive both the conditions of space and the new hostile conditions of our planet, but also the initial effects that launched it into space in the first place.
Finally we have plenty of evidence that suggests life could easily have formed right here on it's own. So even if it did turn out to be true that we have alien organisms running around, it's simply unnecessary.
i disagree with the bible and the nonexistent people we call god and jesus. i believe this theory brought animals and then humans evolved from primates. it is logical and possible.
Extremophiles are capable of surviving in environments similar to those known to exist on other planets. The subsurface water ocean of Jupiter's moon Europa may harbor life, especially at hypothesized hydrothermal vents at the ocean floor.
