Do We Need To Thank Anyone For This Life?

Did evolution begin before there were animals, birds and creatures of the sea? Is humanity the product of a chain of accidents or are we part of a natural and reasonable progression, given the consistency of matter? Is our sense of time a big joke that we are buying into? Was Einstein correct that time is relative? Have we always been living in one continuous present moment that has no past and no future? Is history only for constant reinterpretation of the present moment? Has science adequately and logically explained all of this for us? Just how accurate can science be? Given x-amount of time, is it possible for science to know everything there is to know? What do we do while we're waiting for the truth? What do the next generations do? Or does it even matter? What do the advancements in science and medicine mean in all of this. Is humankind taking control of more and more of the Universe/Creation with each passing year?
Are people better off spiritually today than they were fifty years ago -- 1,000 years ago -- 2,000 years ago?

After pondering on all these questions, are we more likely to think in terms of a Creator God than other choices? Can we depend fully on the Bible? It would seem that there must be something permanent/everlasting. Once we reach a decision that there is a Creator God/Spirit, do we then want to understand our relationship to and with this entity. At creation did God just figuratively "wind the watch", lay it down and walk away, never to return? We'd like to think that there's more of a relationship than that, wouldn't we?
