Do snakes eat dirt?
GEN 3:14 And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
This would only appear as a contradiction to somebody that is unwilling to actually examine the claims made in the Word of God. Do snakes actually consume dust? Yes! It's common knowledge that snakes dart their forked tongue out rapidly, and repeatedly. What are they doing when this is taking place?
Snakes have an organ on the inside of their mouth called the "Jacobson's Organ", which helps the snake to smell things, in additional to the functionality already provided by its nose. The entire process is done through sampling bits of dust and dirt on the snakes tongue.
Aside from this, snakes also attack, and consume, prey from the ground. In doing so, they would be consuming dust, too. You try eating a steak off the ground without getting some dust in your mouth.
Snakes literally do lick, and eat, dust.
