For starts we must decide who our Lord is on all matters in life. They can be from day to day concerns all the way to philosophical issues. I personally do not consider the matter of Young Earth Creationism simply a philosophical issue though. This is a matter that can weaken Christians in their everyday walks with Christ if they take on the world's view. It is easier for many to accept the old earth view because the world around us has made it sound more logical.
Scientific evidence is available to support the young earth.
Here are a few key points. There is a tremendous amount of cosmic dust present in the space around the earth and moon. Because this dust is caught and settled on the moon there was a great concern about the depth of moon dust when our astronauts first went to land on the moon. This was because it was calculated that the amount of cosmic dust collected on the moon over a period of billions of years would make it possible to sink the lunar module deep into moon dust. The fact is, when they arrived on the moon the dust was about an inch or so deep.
