Tip Of My Tongue

I read it during the 80 in a book about various myth from around the world. It was not fiction, all other myths were well-known if obscure (like the Maori creation myth of new Zealand by the demigod Maui) For years now, I tried to find what culture , and what religion this was about without finding. ChatGPT never heard of this story. Here is the story as I recall it:

• A child is born from a burning stone (may be cause it came from the sky)
• A God ( could be his mother or father) hold the burning child with tongs
• The child is then placed in a vial containing a liquid granting invincibility
• As the tong hold the child, his hips did not touch the liquid, thus are is weak spot
• A evil man/god try to kill the child by throwing wheel at him from a mountain
• the child (grown up now) block a wheel with his head, then back, but die when he block it with his hip

Did anyone heard about this myth?
