How was Roger too early to Lodestar?

[Warmmedown]

What do you think that means? Does that give a hint as to what One Piece is?

Did he reach Raftel after that?

I think it was too early to Raftel. There's a prophecy that sounds like Shirahoshi would need to be born along with another person mentioned. Roger was too early to do anything with the knowledge he gained.
