The answer "I dunno" when it comes to these questions is a cop out.
Why? Often it's the most honest answer. Anyway, you're supposed to start by asking questions, not having answers. The whole point it to find answers. Of course many people wouldn't know how to answer from the beginning. Often, the statement "I don't know." is the best place to start from. 'I don't know' isn't the same as' I don't care'.
Also 'I don't care' can also be valid. For example, that last question about the afterlife? I don't know and, frankly, I don't care. I think our focus should be on this life that we are living now. People who are overly concerned with what comes after often lose touch with the things in front of them.
