The word 'true' is a hard sell for anyone to use in conjunction with a theory. But the point is that no one can
prove creationism nor evolution. Simply labeling either one 'true' is in its self an act of faith[In general terms]. I am not sure if you were being sarcastic though.
See, there's a difference between the Theory of Evolution not being provable due to the fact that theories aren't supposed to proven, and Creationism not being provable because it's complete bollocks it's based entirely on unsubstantiated conjecture.
well it is a matter of what you accept as proof or not:
names and dates in book which expresses the view on themselves of an ancient culture which wanted to belive that they are special (these are the words of my RE teacher at school!)
OR measurements and thoughts of people who change their mind very often 'cause someone like them showed them they were "wrong"?
Sadly many people all around this world like things to be constant and safe although life/the universe has not constant and safe things to offer; that is why they make up things like "intellegent design" or creationism
and
Science is and has always not been about finding something solid and safe! from the acient greek philosophers to modern day scientists everyone knew and knows he/she could be prooven wrong one day (although many never accepted to be wrong)
I guess the problem of creationism will live on until someone find a way to proove them otherwise in everyday life (like it was done when it was prooven that earth is not-exactly-a-globe-but-still-something-spherical [I need to be correct with this one!] instead of a plain thing you could fall off from)..
but since the indicators for evolution (I've never heard anyone scientifically debating on evolution using the word "proof") are so abstract things like the physiological analogies between long dead and recent animals/plants and molecular similarities and differences (matches/mismatches in the aminoacidsequences of some "old" enzymes or in the nucleotidsequence of the gens) of rencent animals/plants that ain't gonna happen
