While the biblical story of Noah's Ark is often criticized for being scientifically impossible, this has never stopped people for searching for it. There has been many claims by various groups and individuals over the years saying they had "found" the mythical vessel with no evidence. The most credible person in modern times to look for the ark was astronaut James Irwin who was a devout Christian. He led two searches for Noah's Ark in modern-day Turkey and was disappointed to find nothing. He said "I've done all I possibly can, but the Ark continues to elude us."
