Beginning of seasons only after the Flood

The Beginning of the Seasons Only After the Flood.

Why God didn't start them after the flood. 

A Christian apologetic view says that once upon a time there was a water canopy above the sky. As Genesis says--

 

Genesis 1:6 And God said, Let there be a vault between the waters to separate water from water. 7 So God made the vault and separated the water under the vault from the water above it. And it was so. 8 God called the vault "sky."

The sky trapped the sun's rays so that there was a year-round semi-tropical climate. After Noah’s flood, God commenced the seasons--

 

Genesis 8:22 [God said to Noah] As long as the earth endures, seedtime and harvest, cold and heat, summer and winter, day and night will never cease. 

But the thing is, the existence of the seasons is already mentioned before the flood‑‑

 

Genesis 1:14 God said, Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, 15 and let them be lights in the expanse of the sky to give light on the earth. And it was so. 16 God made two great lights--the greater light to govern the day and the lesser light to govern the night.  

One may wonder what kind of seasons they were. Warm and cloudy ones with soft breezes? Or hot and cold ones, the usual kind.  

The thing is, the earth had seasons before the flood. Despite the apologists.
