If something is inside a car going 80 MPH, that something is also going 80 MPH. I don't know about others on this board where the subject has been debated before, but MacArthur taught Shekinah Glory twenty years ago on television and I agree with him although I picked up the star theory from a big-city planetarium when I was a child. Also, Answers in Genesis (AiG), the world's largest apologetics ministry at this time teaches Shekinah Glory.
Matthew 2:9 (KJV) When they had heard the king, they departed; and, lo, the star, which they saw in the east, went before them, till it came and stood over where the young child was.
"...Two details in Matthew are of special interest. First, the text implies that only the Magi saw the star. Comets, conjunctions, and exploding stars would be visible to everyone on Earth. Second, the star went before the Magi, and led them from Jerusalem to Bethlehem. This is a distance of about six miles, in a direction from north to south. However, not only does every natural object in the sky move from east to west due to the Earth’s rotation, but it is difficult to imagine how a natural light could lead the way to a particular house.
"The conclusion is that the Star of Bethlehem cannot be explained by science! It was a temporary and supernatural light. After all, was not the first Christmas a time of miracles? God has often used special, heavenly lights to guide His people, such as the glory that filled the tabernacle (Exod. 40:34-38) and the temple (1 Kings 8:10) and that shone upon the apostle Paul (Acts 9:3). Such visible signs of God’s presence are known as the Shekinah Glory, or dwelling place of God. This special light is a visible manifestation of divine majesty. The great mystery of the first Christmas is not the origin of its special star. It is the question of why the Magi were chosen to follow the light to the Messiah, and why we are given the same invitation today."

As for the dinosaurs, AiG teaches that they were on the Ark. However, afterwards the world was greatly changed and they did not adapt and may have been purposely hunted down and killed by men because of the threat that they posed.
On the issue of the Woolly Mammoth, Young Earth Creations have the best explanation for it. Essentially, they believe that it was trapped in dust storms like those of the American Dust Bowl or worse but associated with the Ice Age.
