Conclusion
The mounting evidence from biology, geology, and astronomy points to a tantalizing possibility: life on Earth may have cosmic origins. From organic molecules on meteorites to resilient microbes and laboratory simulations, each clue strengthens the panspermia hypothesis. Ongoing research continues to push the boundaries of our knowledge, challenging us to rethink how—and where—life begins.
As we explore further, we may discover that we are truly citizens of the universe.
