Is there any preposition like "for that" ?

Hello everyone.

Sometimes, I find "saying because" to be boring.

What kind of prepositions can I use instead of "because" ?

Especially, I want to learn whether there is a preposition like "for that" or not.

For example,

Can I say: "For that you came here, I am thankful to you."

instead of "I am thankful to you because you came here."

or

instead of "I am thankful to you as you came here."(I think that it is also usable.)

Thank you very much in advance.
