Debunk creationists argument with simple math
A common argument put forward by creationists is that the evolution of complex systems, such as the eye or the brain, is so improbable it is practically impossible. This argument, at first sight, appears to be fairly powerful and I haven't seen it demonstrably countered, even by 'The four horsemen'.
This 10 minute video is the best I have seen so far that explains, in simple and powerful terms, how complex systems evolve out of apparent random chance without the need for massive probabilty numbers.
Even those poor deluded people with IQ issues should be able to understand it.
If you like it and feel it will be useful, please pass it on.
Keep it real,
