So, all those things were different, you say?
Where is your evidence to show that plant growth rates were different?
The evidence is in the record. The Scripture record. Man cannot know by science or any other way.
And how were they different? Were they faster or slower, and by how much?
Faster. A tree could grow in weeks to bear fruit, even less.
How did they photosynthesize at a greater rate to provide the energy needed for a faster growth?
Who says that was the way growth happened? Have you some proof of that claim?? If so we can look at it. Light exhibited different properties, so even if you were correct, that would be child's play to answer.
How were their root systems different to account for the different amount of nutrients they needed to extract from the soil?
Got any root systems from pre KT layer? If so, we can look at that.
Where is your evidence to show that lifespans were different?
You cannot know by science that people even lived at all!!! They did not leave remains as we would in this state, so science foolishly has thought there were no people!!!!!!! You guys are in kindergarten.
How did they survive the illnesses that older people suffer from?
How will they survive soon in the time right after Jesus returns to rule forever? How does the tree of life work? What laws and forces work together when a new state exists that includes spiritual matter? Many questions are just too big for science! The bible does give some clues though.
How could the towns support such a large population (they had to house and feed and support not only the current generation, but the one before that, and the one before that and so on going back several centuries if the Bible is to be believed).
If plants grew fast how hard would it be to grow food in days??
Where is your evidence to show that light was different?
Adam saw stars.
In what way was it different?
In the future a rainbow can have an emerald appearance. Light also comes from God, and we will not need the sun.
Was it still made up of photons? Was the energy carried by a single photon different to what it is today? If so, was it a smaller or greater amount of energy, and by how much was it different?
Apparently the light of eternity doesn't burn like our light. It can be invisible to the eyes now also, and beyond our range and usual spectrum. Paul saw a great light, but those with him saw nothing.
Did light travel at a different speed?
It may not be the speed that matters. You see if time does not exist, or exists in another way, then the time it takes light to move would be different!
If so, was it faster or slower, and what was the speed it travelled at? What process or mechanism caused it to change speeds to the one we see today?
As above, perhaps time was a factor. Also, the universe is linked to God and His will. So we need not have one universal speed of light! It may depend on how fast we or God want it to get there!?
Where is your evidence to show that thermodynamics were different?
The water and land on the planet was separated and no great heat produced.
Who says these existed as we know them?? Proof?
If so, please explain how it was different to what we have today. Also explain the mechanism which changed the law to what we have today.
God is not a mechanism.
Please define spirit and provide evidence that spirits have ever lived on earth.
A spirit is a being that has a body that is not physical, and has certain properties, largly unknown to man. Some properties are known, such as an ability to pass through matter.
Please explain what mechanism allowed the genetic changes that occur in evolution to proceed at a more rapid speed in the past state. Please also explain why this rapid evolution is no longer possible today.
Science doesn't know. Some knowledge, if wicked mankind knew, they would be too dangerous.
Please show me the evidence to indicate that all of the surface of the world was covered by water at one time.
My current guess for the aprox layer where the flood was at or near is the KT layer. The iridium comes from space or deep in the earth, just as the flood waters came from the same places!
Got any tough ones now?
