Expressions: It seems necessary / To be necessary

[Fan of Arabian horses]

Hi!

Are the above expressions correct and which of them sounds more natural?

For Instance:
It seems necessary/..to be necessary to ask this question, as Google didn?t offer me a satisfying answer.

Thanks

It seems (to be) obvious/ridiculous/etc that...
