Is it scientific to conclude that God is an unreliable eyewitness?
Well... if HE doesn't speak DIRECTLY to YOU, then yopu have to rely on others for input.
Who knows, they may have faulty memory, or have an agenda, or an ax to grind, or be mentally off or (Heaven forbid!) a liar.
Tell him to show up for an eye exam and then we'll know how good of an eyewitness he might make...
