Just like so called "global warming'...

Scientists are always guessing on what they think... no one really knows it's all a guessing game.

These footprints are older than feet

 

[Old Rocks]

Unlike the thought processes of the 'Conservatives', scientists can accept new evidence and data, and incorporate it into the data and evidence that they already have. There is nothing at present that says another species could not develop feet similar to ours and walk upright. And I would also double check the dating on the rocks where the footprints were found. That is SOP in science. We don't go off half-and stupid the way that you people do.

As for global warming, you can argue with all the Scientific Societies, all the National Academies of Science, and all the major Universities in the world, all of which have statements of policy that state that AGW is real, and a clear and present danger. You can argue with them, but nobody with half a brain is going to listen to a retard with no scientific education.
