Riding the arrowhead of time

As far as I'm concerned, we God-created evolving humans are riding this arrow of time, we at the arrowhead with the future rushing toward us like a desert zephyr, yet still the most tinniest speck of time is all that we know, but behind are sands and rocks and mountains of time past. Still, we are the culmination of the past, all the past that evolution attempts to describe the building of, and what is it that we must carry on? Carry on to a distant future? A future that will find the children of ten thousand generations of our great grandchildren -- they -- they then will be riding that arrowhead, and they will carry that riddle that must never be lost. The riddle of the ultimate why. Why life? Why are we here? For what purpose and point? For if this quest for answers is tossed aside as being pointless, then will all those past evolutionary forces that produced within us a questing will to seek the unknown be all for naught?
