It's pretty much been shown that rocks could have been thrown from Earth to Mars and visa versa during meteorite strikes so they could have got around.
I hadn't realized there was a project to drill 2m holes into Mars and look for signs of life that was supposed to fly in 2022 but it was in cooperation with the Russians and all fell apart due to the war. https://en.wikipedia.org/wiki/Rosalind_Franklin_(rover) https://en.wikipedia.org/wiki/Rosalind_Franklin_(rover)
- ozim 2y agoI fail to imagine meteorite event that could throw rocks to stable orbit earth let alone go to the Mars. I guess over eons everything is possible and didn’t do any math but my understanding of physics is saying „not possible”.

Obviously you need a big bang to overcome the Earth's gravity. Here's a NASA guy trying to simulate it in the lab https://youtu.be/bfrHoGlFLwk?t=70 https://youtu.be/bfrHoGlFLwk?t=70
