Perhaps you should start reading your Bible.....
Lev. 24:17-18, Num. 31:25-28, Rev. 16:3
Just a few examples. If God says animals have souls, I'll take HIS word for it....certainly not yours.
This status certainly wasn’t bestowed upon plants, and the bible creation account uses the Hebrew term for soul, “nephesh,” over and over about what modern biology refers to as the higher animals. (Insects don’t seem to qualify.) Some aver that this refers to breathing; however, “nephesh” is used also to refer to underwater aquatic creatures.
