Thanks for this, I do not agree with the drake equation, but I agree that it is a good tool for discussion, that is where it falls down in presentation, each of the aspects is open to speculation, you tried to remedy this with your 3 point approach, but using the Drake Equation like this leaves me with many questions. Too many for this comments section.<br>I totally agree with all your takeaways. I think that studying ourselves and our own planet is key to being able to exist on a different planet. I believe there are some things we will discover that will make it easier for future colonisation of planets, and the quickest way to do this is to learn to work together. I hope that will become possible, in all aspects.
