WHY GOD CREATED REPTILE

What about the snake in the Garden of Eden?
I have a Genesis Bible question: When God ‘found out’ that the serpent had deceived Eve, He cursed him and commanded him to crawl on his belly from now on it was establish.
Now, I take it that the ‘serpent’ was a snake and that is the truth, But Satan was only using the FORM of a snake for his purposes.
Why curse an entire species of animal for something Satan did? And did this mean that snakes didn’t ‘crawl on their bellies’ before God cursed them? THAT IS A NICE QUESTION TO ASK.
The snake imagery is picked up in Genesis 3:15 when the snake is told.
The snake was cursed to crawl on the ground and therefore susceptible to man’s heel crushing its head (this vulnerability is a direct result of Satan’s sin). This is a foreshadowing of what will really happen to Satan someday.
The seed (Jesus Christ) of the woman will crush the head of Satan and His heel will be struck TALKING ABOUT THE CRUCIFIXION OF CHRIST in the process.

In addition, the curse upon the physical snake was reflective of the actual curse upon Satan himself: crawling low on the belly was a mark of deep degradation , It is writrn in the book of (Lev 11:42) and eating dust was also a sign of despair (Micah 7:17).
All these factors combine to form very vivid symbolism of what awaits Satan in the end.
MAY GOD HELP US MAKE HEAVEN AT THE END.
