Life in our solar system might be of local origin. I remember reading articles in the last few years hypothesizing that the earliest life might have formed on Mars, where conditions were even better for microbial life than Earth billions of years ago. There was a lot of meteoritic bombardment during the Hadean period, some Earth meteorites DID come from Mars, some Earh microbes are still hardy enough to survive crashing through our Atmosphere, so it’s conceivable that some microbes may have hitched a ride way back when.

Of course early Mars was far different from what it is now. Mars looks like a lousy place to look for life these days, but some of Jupiter’s and Saturn’s moons may have “seeded” by other hitch-hikers on other meteoroids, so who knows?
