Hi how are you
I forgot the name of the manga or webtoon can't remember
The story is about a being very powerful going through several rebirths
The final rebirth is becoming a human with super powers as a child. after they killed his human mother he decided to kill all human beings
And later on he was hit by a car and lost his memory and was adopted by a young girl, she was the one driving
The girl was working in a lab
Where there was another test subject which was the same origin as the hero....
So I can't remember the title
Thanks in advance

Existence (Gwang Jin)

Thank you so much that's the one I'm looking for 🙂
