The bottom line is that the evidence of an old earth is as overwhelming as the data that the earth is an oblate spheroid that orbits the sun, and thus "Young Earth Creationists" (YEC) are no less foolish than "flatearthers" and "geocentrists" in their mistaken beliefs (in fact you could say that the evidence for an old earth is more accessible and easier to comprehend than the evidence that invalidates the geocentric model of the universe).
This part of your paragraph designed only to inflame creationists and feed evolutionists ego should be removed from your opening statement.
If I said the evolutionists are a bit flat headed (foolish) for believing in an old earth based off the evidence. You would take offense and cry foul (not because I believe the evidence is overwhelming) but because the implication that evolutionists are foolish flat heads is an inflaminatory statement.
Thank-you,
