    May not have come from a planet. There’s a theory that the young universe was at habitable temperatures literally everywhere at one point, so it would have been trivial for life to begin. Plus the universe was way smaller and denser than, so it would have been easier for that life to travel everywhere.

    Literally any rock in space could have life hidden in it.

      I think you mean “hypothesis”

      Plus the universe was way smaller and denser than, so it would have been easier for that life to travel everywhere.

      There was a significant - over half a billion year - gap between the formation of the Earth and the earliest traces of life.

      Was the gap between Earth and the Sun habitable during this period?

        Yes, it’s a hypothesis if you want to be strict about it. I don’t feel like arguing with a pedant today so here’s a short paper for you to read about a proposed habitable cosmological epoch: https://arxiv.org/pdf/1312.0613

          Abraham “Avi” Loeb

          In 2018, he suggested that alien space craft may be in the Solar System, using ʻOumuamua as an example. In 2023, he claimed to have recovered material from an interstellar meteor that could be evidence of an alien starship, which some experts criticized as hasty and sensational, and other experts showed that Loeb mistook ordinary truck traffic for a seismic evidence of the meteor, causing him to look hundreds of miles in the wrong direction.
