That could happen without evidence But scientists seem to think that the evidence is overwhelmingly in support of evolution –How could they miss Hovind’s simple alleged disproofs?

Science isn’t a popularity contest –This isn’t the X-Factor –We don’t vote off the theory with the stupidest name The truth is determined by detailed argument, evidence- based discussion, statistics, etc. It takes seconds to make a false statement, and (potentially) hours to prove that it’s false –E.g. saying that ‘radiometric dating is unreliable’ takes three seconds –Showing why it is reliable requires a complete explanation of the entire technique, which would take ages Especially for anyone not familiar with exponential mathematics, nuclear physics, chemistry, geology …

Maximinus Thrax was 8’6” tall? –Cited in Historia Avgvsta –Almost certainly fictional The work cites fictional authorities Skeletons of giants –There are several stories, but zero evidence –Provide one single giant skeleton and the argument is over

They are held because people want or need them to be true, not because they are true They can sometimes seem very convincing
