Many people claim to have seen Noah's ark, there is a lot of evidence for it too. Let's look at the two most popular ideas about where the ark landed
Genesis 8:4
Then the ark rested in the seventh month . . . on the mountains of Ararat.
We know from the Bible that the ark landed on the "mountains of Ararat"
The most common place people say they have seen the ark is on a mountain called "greater mount Ararat". Most of them describe similar things about where the ark is at.
Some people say the ark is in an area at the base of the mountain and has rotted away. There is a boat shaped object there that is the same size as the Bible says the ark was.
No one knows for sure if the ark is at either of these places, but believe God first and what He says in the Bible, the evidence will not dissapoint you then. We know that somewhere in those mountains of Turkey the ark landed. We don't know what happened afterward. Perhaps Noah and his family tore it down to build homes with? Or maybe it was destroyed when the mountain erupted (it is a volcano). Whatever happened we know that God's word is always right.
