The Earth's Tilt & The Ice Ages
The great variation in the earth’s tilt is proof that the earth is billions of years old. The earth has been through 6
ice ages over the last billion years. They have occurred about every 150 million years and have lasted about 50million years. The last ice age began 65 million years ago.
The Facts Are .....
The great variation in the earth's tilt does not necessarily mean that the earth has been around for billions of years. Measurements of its changing tilt over the past 3,000 years can be explained very satisfactorily by an asteroid impact which formed the Pacific Ocean Basin, uplifted surrounding mountains and caused associated volcanic activity and earthquakes. 
Meteor impact can easily explain every geological feature on earth. An analysis of the earth's geology suggests that there is no subsurface energy source capable of sustaining enough power for 5
billion years so that it could create new landforms and mountains, cause earthquakes and volcanoes, or renew the continental uplifts. According to one theory, geological phenomena are created immediately as a result of meteor collision, with basins at the point of impact and the force instantly building mountains and uplifting continents. If this theory is correct, the age of the earth is not enough to justify evolution. 
Australian astronomer George Dodwell, using reverse projections of the movement of the axis of the earth, has found that the earth had a sudden, dramatic tilt of its axis in 2345 B.C. The resultant wobble of the axis produced a curve that allowed the readings to fit perfectly the solar calendars of Eudoxus, Stonehenge, and the Solar Temple of Amen-Ra (these have been regarded by modern astronomers to be grossly in error). He believes that a possible explanation for the axial shift is an asteroid impact in the Pacific Ocean. 
The idea of Ice Ages has been widely propagated by geologists to explain certain geological formations. The common belief expressed is that these Ice Ages were caused by periods of incredible cold caused by sunlight being blocked from striking the earth's surface. Logical analysis of this scenario shows that the existence of a vast expanse of ice containing millions of cubic kilometres of water could only have formed if the world was actually warmer, where the energy input could produce such consistently large volumes of precipitation over an extended period.

"The skin of the mammoths show that they were almost certainly not particularly adapted to Arctic conditions any more than the great cats, bison, wolves, bears and horses which have been found buried in the same layers. Thus, when we think of mammoths, there is no reason to see them as necessarily associated with ice while they were alive. Mammoth bones have been found in Mexico." 
The fact that mammoths have been 'snap-frozen' with food remaining in their mouth and stomach is not satisfactorily answered by the Ice Age theory. The Ice Age is believed by evolutionists to have started about two million years ago and terminated about 11,000 years ago. The mammoth cryogenic entombment suggests a rapid rather than a protracted freezing event. [based on logic]
What happened to the earth during the Ice Ages is not a known fact, but rather, supposition and postulation. For example, it was once commonly believed that North America was covered with multiple, huge ice sheets. There is evidence that the area was only covered by one thin sheet of ice, and that there was only one Pleistocene Ice Age.
