The video explores the intriguing possibility that human DNA might have cosmic origins, potentially predating Earth itself. It discusses how components of DNA, such as carbon and nitrogen chains, could be older than our planet. The video presents evidence of organic molecules found in space, suggesting that life's building blocks might have been delivered to Earth via meteorites. The panspermia theory is introduced, proposing that life could have spread across the universe through cosmic dust and asteroids. The video concludes by pondering the implications of life having cosmic origins, including the potential existence of intelligent life elsewhere in the universe.
