While I recognize your logic, and even mostly agree, the point still stands that it cannot be conclusively and definitively said (as least as far as we've been alive/can tell) that hundreds of tons of Martian meteorites fall to Earth every year. Or even tons at all.
Tons of meteorites in general, sure — but not from Mars.
- ceejayoz 2y agoIt is likely given these numbers at least some tons of Martian rock land here annually, which makes the seeding of life concept feasible. I'm on board with "not hundreds of tons", but it's a lot closer estimate than 277 ever. (48.5 * 365) * (277 / 72,000) = 68 tons per year as an extremely speculative estimate here, ignoring entirely probable variances in what hits us (much of which is sand-grain sized) versus what we identify... and again, any estimate here we have to multiply by a few billion years.
