3 Reasons to Believe Dinosaurs Were on Noah’s Ark

1. Dinosaurs and Humans Were Created on the Same Day

The Bible teaches that all land animals—which would include dinosaurs—were created on day six—along with Adam (Genesis 1:24–31). Romans 5:12 says human death entered the world through Adam’s sin, affecting all creation (Romans 8:20–22). If death followed Adam’s sin, then dinosaurs couldn’t have died off before humankind was created. Scripture supports the conclusion that humans and dinosaurs coexisted.

2. Dinosaurs Were Alive at the Time of the Flood

A global, catastrophic flood would have laid down vast sedimentary layers across continents, packed with marine and terrestrial life—exactly the sorts of deposits in which we find dinosaur fossils today. These layers preserve dinosaur footprints, hatchling nests, and animals frozen mid-interaction. Such evidence aligns with the biblical description of a flood that progressively overwhelmed entire ecosystems, including those that contained dinosaurs.

3. Dinosaurs Fit the Description of Ark Animals

Due to rampant wickedness, God sent the flood to wipe out humanity, clean and unclean beasts, creeping things, and flying creatures. But Noah found favor in God’s eyes, and God instructed Noah to preserve these groups by keeping representatives alive on the ark. Genesis says every kind of land-dwelling, air-breathing animal boarded the vessel. As air-breathing land animals, dinosaurs fit this description.

Some people question how such towering creatures could have squeezed into the ark. But over half of the known dinosaur kinds were smaller than an American bison, and even the largest were small as juveniles. The ark didn’t need to carry full-grown adults, just young representatives of each kind. Like elephants or rhinos, they would have qualified—and fit—as ark passengers, preserved according to God’s covenant promise (Genesis 6:18–20).
