Did it rain before the great flood - Noah and the Ark?
God tells us that after the world was created, rain did not fall to the earth. There was no rain.
Now no shrub of the field was yet in the earth, and no plant of the field had yet sprouted, for the LORD God had not sent rain upon the earth, and there was no man to cultivate the ground. But a mist used to rise from the earth and water the whole surface of the ground. (NASB) Gen. 2:5-6
God watered plants and trees by using a mist which woud cover the ground. Rain did not start falling on the earth until God caused the flood to occur.
For after seven more days, I will send rain on the earth forty days and forty nights; and I will blot out from the face of the land every living thing that I have made. (NASB) Gen. 7:4
The flood started when the rain started to fall (Gen. 7:12), and the water from the oceans surged upward because of the shifting continents. The flood stopped when the rain stopped, and the water below the continents stopped flowing up (Gen. 8:2). After the flood, we read about rain throughout the Bible. Rain becomes a normal event.
After the flood God placed a bow in the sky as a reminder that He would not destroy the earth again with water. Thank you God for the rain and for your mercy.
