In Genesis, what was Noah’s first recorded act after the Floodwaters receded?

In Genesis, Noah’s first recorded act after the Floodwaters receded was building an altar.

Genesis 8:20 records Noah constructing an altar after leaving the Ark. He then offered burnt offerings from animals and birds identified as clean. The verse marks the narrative’s immediate transition from survival on the Ark to life on the restored land.

This question can be confused with several nearby events. Noah released birds before leaving the Ark, and he planted a vineyard later in Genesis 9. The altar is the first action explicitly narrated after Noah exits with his family and the animals.

The episode is followed by God’s covenant with Noah and all living creatures. That covenant includes the promise never again to destroy all flesh by a flood, with the rainbow presented as its sign. The sequence is altar first, covenant next, vineyard later.
