This is science.
Scientist today can go out and make measurements an calculations on the information that they have. For example.
There is a certain amount of meteoric dust, that the earth and the moon accumulate, at an essentially constant rate, if the earth is indeed 5 billion years old like evolutionist insist, then there would be a layer of it 182 feet thick. Nasa was worried about this, but worries proved unwarrented when we landed on the moon and measured a layer only an eighth of an inch.
Many creationists bring up that point, but its flawed. The person who tested the dust (Hans Pettersson) went to the top of a mountain with a smog level detecting device and collected nickle particles in the air assuming it was meteoric. He concluded that 15 million tons of meteoric dust enters the earth every year. Fast forward a few years and scientists measure the dust again (this time, correctly) and through multiple tests they come up with 20,000 - 40,000 tons a year. The several hundred feet of dust? The earth creates millions of tons of dust a year just from corosion, space dust wouldn't effect anything.
The moon does not have its on corosion, so its only form of dust is through foreign sources and it only gets 840 tons a year because of its gravity. The moon has a layer of loose dust, but under that dust is rocks mixed with compacted dust. Nasa was not worried about how deep the dust was, they and the soviets had launched unmanned missions to the moon before, they knew what it was like way before they set foot on it. You shouldn't use the dust theory, even well known creationists dismiss it
Another evidence for a young earth is provided by the small amount of helium in todays atmosphere. Evolutionist think that the radioactive decay processes of uranium and thoruim that produce helium have been occurring in the earths crust for billions of years. But if this was true there would be much more than the 1 part in 200,000 of helium.
Helium cannont escape through the atmosphere like hydrogen does and to add to this it is probable that helium is actually entering the atmosphere by means of the suns corona. Calculations on available figures is that to get the amount of helium through natural alpha decay is approximately 10,000 years.
There is more too, but im tired of typing.
"Banks and Holzer (12) have shown that the polar wind can account for an escape of (2 to 4) x 106 ions/cm2 /sec of 4He, which is nearly identical to the estimated production flux of (2.5 +/- 1.5) x 106 atoms/cm2/sec. Calculations for 3He lead to similar results, i.e., a rate virtually identical to the estimated production flux. Another possible escape mechanism is direct interaction of the solar wind with the upper atmosphere during the short periods of lower magnetic-field intensity while the field is reversing. Sheldon and Kern (112) estimated that 20 geomagnetic-field reversals over the past 3.5 million years would have assured a balance between helium production and loss." ("How Old Is the Earth? A Reply to ``Scientific Creationism'' Dalrymple, G. Brent ).
Henry Morris (the man that wrote the book with all the theories you posted and on every creationist website) ignored science and processes in which to measure things to further his beliefs.
