"20 Then Noah built an altar to the Lord and took some of every clean animal and some of every clean bird and offered burnt offerings on the altar. 21 And when the Lord smelled the pleasing aroma, the Lord said in his heart, “I will never again curse the ground because of man, for the intention of man's heart is evil from his youth." ---What cursing of the ground is he referencing? Is it the cursing of the ground by way of the when Adam and Eve's sin caused the earth to produce thorns and such, or is it from when Cain was cursed that the earth would not yield for him? ---Further, why did God curse the gound when it is humans who are evil? "Neither will I ever again strike down every living creature as I have done. 22 While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease.” ---What does this mean? Is it implied that since the days of Cain that produce didnt grow (and that was by way of the seasons not doing their thing)?
