What was the first thing Noah built after leaving the ark?

The first thing Noah built after leaving the ark was an altar.

Genesis 8:20 says Noah built an altar to the Lord after the Flood and offered burnt offerings from the clean animals and birds. The scene marks a transition from survival inside the ark to renewed life on the earth. It also precedes the covenant described in the following verses.

The altar is not described as a settlement, house, or city. Noah’s later story includes vineyards and family events, but the first construction specifically mentioned after the ark opens is the altar. This detail is sometimes overlooked because popular versions focus on the animals leaving the vessel.

Genesis says Noah took some of the clean animals and birds for the offering. The text therefore distinguishes the sacrificial animals from the broader animal population preserved aboard the ark.
