the sun loses millions of pounds of weight per second there for it used to be bigger a bigger sun 10 000 or more years ago would have cooked us.
the earths spin slows down every 2 to three years about one second which means it used to spin at a faster rate. 6000 years ago a day would have been 23 hours which would not have been a problem but half a million years ago the earth would have spun several times an hour, big disaster.
the moon gradually leaving earth indicates that the earth is not that old. you see the moon creates the tides and if it was closer then the speed it is moving at over the last 50 000 years we would have waves taller then mount everest.
the rings around saturn are slowly leaving the planet this also indicates that saturn cant be old
the oldest desert on earth (the Sahara) is only 4200 years old. it started after the flood by the way.
the oldest dated tree 4300 years old.
there is only a few thousant years of mud build up in the ocean.
I can go on for ever, but this should keep you guys fired up for a bit
oh by the way if you are wondering what happened to the dinosaurs, they died in the flood.
