The Universe is Younger than We're Told

Evolutionary cosmologists postulate an old universe based on their presuppositions. When facts are learned that contradict their belief system, they need to tap dance around them or modify their theories. (Of course, modifying theories to the point that they must discard an ancient universe viewpoint in favor of a young, created universe is unthinkable to them.)

Their modified viewpoints often create more questions and problems than they solve, such as the imaginary Oort cloud, abode of comets in waiting; there is no evidence that such a thing exists, but it conveniently explains away the fact that short-term comets should have been exhausted long ago.

Other bafflers for cosmologists include methane in the thick atmosphere of Titan, the hypothetical temperature of the sun 3.8 billion years ago and the heat of Jupiter's moon Io.

Biblical creationists do not need tap dancing lessons for their theories.
Accepted theories of evolutionary science say our Earth and our solar system formed about 4.6 billion years ago. On the other hand, the Bible implies Earth is only several thousand years old. Further, Genesis 1 and other passages such as Exodus 20:11 imply that everything in the physical universe was created in the six-day Creation week. Thus, like Earth, the solar system also is only thousands of years in age. Is there scientific evidence that our solar system is not billions of years old? Yes! And this evidence is posing a mystery for scientists who believe in billions of years.
Evolutionary theories propose that our solar system formed from a large spinning nebula in space. 
The nebula is believed to have flattened to a spinning disk of gas, dust, and ice known as the accretion disk. Over millions of years, gravity caused the planets and other objects to form from this disk, and then excess gas and dust dissipated and cleared away, leaving the solar system as we see it.
