Thoughts on the Drake Equation

Stu21

So I guess that in the end the Drake equation holds a lot of value in that it is giving us a reasonable estimate based on the reliable information we've so far managed to gather.

One thing i'd still like some clarification on though; out of all this i'm getting that the biggest problem with the Drake equation right now isn't the variables, its the lack of strong data about the variables, would i be right in assuming this?

A lot of good answers though, thanks to all.

Stu21, look into the Rare Earth Equation. It adds a ton of variables to the Drake equation. Whether you agree or disagree with its conclusion, it should give you more food for thought as to the rarity or lack thereof of the conditions needed for Earthlike conditions. It is by no means the end-all, final word on the subject, but it has some fascinating analysis. It's conclusion , as you might expect, is that Earth is rare indeed! You can find more info in the book "Rare Earth".
