If life started on other worlds, it might have had a head start compared to whats on earth. So there could be some advanced life forms that might consider the earth as a farm, laboratory or a zoo.
"Extra dimensions of space—the idea that we are immersed in hyperspace—may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still--but ultimately hit a dead end. Modern research has advanced the subject in ways he couldn’t have imagined. John Hockenberry joins Brian Greene, Lawrence Krauss, and other leading thinkers on a visual tour through wondrous spatial realms that may lie beyond the ones we experience." https://www.youtube.com/watch?v=h9MS9i-CdfY , https://www.youtube.com/c/WorldScienceFestival/videos
What if the universe has not only many more dimensions, but many channels or layers to it?
"Proposed a century ago to better explain the mind-bending behavior of the smallest constituents of the universe, quantum theory has implications far beyond the atom. This rich set of laws has applications both practical and extraordinary — from the technology that has revolutionized modern life to the possibility of parallel worlds." https://www.youtube.com/watch?v=IxRfDtaot5U , https://www.youtube.com/c/WorldScienceFestival/videos
What if the known universe is but one of many?
"The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Join physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom as they discuss and debate this controversial implication of forefront research and explore its potential for redefining the cosmic order. Moderated by Robert Krulwich and featuring an original musical interlude, inspired by parallel worlds, by DJ Spooky." https://www.youtube.com/watch?v=OO4uzgiRHkE , https://www.youtube.com/c/WorldScienceFestival/videos
