  1.  @MOEMUGGY  Well, I agree that Earth may have been seeded! I'm just asking, are we sure biogenesis didn't happen a million times on Earth? I'm not ready to assume it only happened once. Due to competition, perhaps most of the early experiments expired, or perhaps some even fused so that our "single lineage" Earth life is really a hybrid lineage. Anything that happened really early -- before the first cells -- is pretty much unknown territory.

  2. There's an observation bias, however. A planet farther out is less likely to get tidally locked, and is also harder to see...

  3. I wonder how many species visit Earth in a typical tourist season

  4. To be fair, Fravor and others often do say that they seem like not current human technology. So FLIR is fair game. Aliens is one of the least strange explanations

  5.  @visvivalaw  Sure. But it's not a problem to speculate. They are so strange that "aliens" has to be on the table.

  6. yup... one origin a billion years ago could have seeded the galaxy

  7. even atoms have an element of consciousness, so a bottom up process is in a way also inspired by the top, if you get my drift

  8. life finds a way

  9. I think it is teaming with living things, but we'll see! I think many of them are visiting earth because it is rare, but not alone

  10. biogenesis might have happened many times, we only see the winner

  11. then i would expect life forms across large patches of the galaxy to share a common ancestor

  12.  @sexgod57able  I'm thinking that these very rare intelligent life form could decide to spread life around all the stars in its local area, leading to patches of star "empires" that would still not contact each other because they begin so far apart. But yeah I do tend to think abiogenesis is probably fairly common, which would lead to contact eventually.

  13. competition may be a factor preventing new forms

  14. former head of Space Security for Israel...

  15. there is time in the equation though

  16.  @totalermist  ah yes, the dynamic nature would change everything. Good point For example... what is the rate at which a civ colonizes a new planet? That could be key, but it couldn't be put into a static equation even if we knew the value!

  17. imagine if dolphins and octopus got together with the electric eel, they could probably smelt metal from nodules and make stuff.
