If your immortal soul is the issue and return to God the goal, why exactly are you bothering with past and unrelated things of this world? You know who the lord of the earth is, so why would you look to his works and his record to confirm the validity of his foe?
You either know, or you dont know, and no dinosaur is gonna prove it either way to a nonbeliever.
You will not win converts with this endeavour, and in the end, it is an unimportant distraction. You may as well ask which is more unlikely, but you are unsure and therefor cling to unimportant bits of worldliness. Remove the log in your own eye and worry not about passing judgment on others. You will do better works by being honest and appropriate than being strident and tangential.

And for you assholes that think this is only a christian issue, there are nonchristians that take the words of the OT as literal truth, and if you diss them they will kick your ass and call you an antisemite
