Hi I am a marvel fan converted because the MCU got bad.

I have started reading gritty comics like Green Lantern Blackest Night and Death of Superman because I like when heroes are realistic and can die.

Please be kind to me because I am kind.

For my first question I want to ask why was Superman a virgin birth? I do not understand why he was made in a vacuum and not conceived naturally so he was accidentally born on earth?

Is this?
