Looking for a Sign of the End

want a sign that the Bible is true. Many seek factual proof for the Historical Jesus and are seeking a sign of the validity of the Bible, such as Noah's Ark or the Ark of the Covenant. The believer accepts the Bible as valid, but judging from the many explorations they still seek a sign. There have been many attempts to find Noah's Ark, the ashes of the Red Heifer, the garden of Eden and reports of finding the Ark of the Covenant, but none have been found. Christ said in Matthew:
"A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah." Matthew 12:29.
