Why wasn't が used instead of には in [そんなこと、私にはとても出来ない。]?


Why wasn't が used instead of には in

> [そんなこと、私 **には** とても出来ない。]?

Is it correct to use が? What is the meaning/sense and role of には in the
sentence to choose it over the が particle?

English:

> There's no way I could do something like that.

Note!! Same phenomenon in [この本の漢字は難しいので私にはとても読めない。].




私には the emphasis is on the "I", suggesting that perhaps some other person may
be able, but I am not. Typicaly this is regarding some skill.

With が the emphasis would be more neutral, or even focused on the 出来ない．

These forms may also be used in a sense like "I could never do that!" again
emphasis is up to the speaker.
