I suggest directing some of your curiosity towards Google. This topic has been discussed many times before. In short: Your notion of "cause and effect" is not necessarily meaningful or applicable to all aspects of nature. Time could have been created in the Big Bang.

Also, it's possible that the entire process was continuous... the closer you rewind towards the big bang, the longer it takes to rewind just a little bit further.

Thanks for the link, it's interesting read. Even if time is created with Big Bang, and there are probabilistic quantum processes that don't demonstrate "cause and effect" in traditional sense these explanations come down to some singularity and suggest to accept that singularities just happen.
