Why Prof. Oak is NOT Ash's dad.

I agree.
Also, Delia seems pretty young and Prof.Oak is like old. Also i cant imagine him and Delia ..... i think i will stop there.
Unless, Professor Oak is also Ash's grandfather, and Delia married Prof. Oak's son. Then Ash and Gary could be brothers ....... but i prefer my other story where Ash's dad was fryed によって Zapdoes

Well Ash is 10 and Prof.Oak is I think over 50 o maybe even over 60 years old.(yes I'm thinking back too Pokemon 4ever)

So its is very unlikely and now well I'm thinking to (great cannot remeber the name)Spell of the Unown in the photograph of Delia,Oak and Molly's father(Sorry can't remember his name) Delia dosen't even look 10 and Oak looks the same age so my coclusion is Oak is not his father but I have a strange thought of who his father might be...(see picture) BUT that would mean that Silver an Ash are brothers...

That's not true. People can have もっと見る than one child - why nearly everyone in the Pokemon fandom seems to forget this, I don't know. Ash would be Gary's uncle, not his father. I'm only 7 years older than my oldest nephew, and I used to know a kid who's aunt was younger than him - he was 6 at the time, and she was 2! So, it's certainly possible.

What?!! Gary could not be Ashes son! There baceackly the same age!

Ash and Prof. Oak are not related in any way besides the fact that they in "Pokemon 4ever" Ash becomes フレンズ when a young boy named Sam Oak (Prof. Oak) who travles to the future with Celebi. (Highly reccommend watching it btw). As to why Prof. Oak never tells Ash that he's Sam i dont yet understand, but it becomes clear in the movie that he is.

I know the 人気 theory about the GS Ball these days are that Gamefreaks wants us to forget it because they made a movie about Celebi instead. But i think that Prof. Oak might know exactly what the GS Ball is all the time and just gets Ash to bring it around for him in hopes that HE will figure it out. This wouldnt ruin the "Ash can't catch a legendary" thing gamefreaks has going either, seing as he didnt "catch" Celebi.

Hope the first part 回答 your 質問 properly, and for the 2nd part im just hoping someone will find my theory as interesting as i do :)
