Seeing as our in-house JW's are too scaredy to come and answer these questions, I shall take on the challenge! (All answers provided by JW Parenting™)
How did all the diversity and unique life that has been discovered in the past century in the south american rain forests and austrailia get from the Ark to there respective places?
God controlled the animals and moved them where he wanted them. There may have been land bridges for the animals to use.
If it was so important then why didn't God just recreate them instead of creating such an impossible task for Noah?
But the task wasn't impossible, because Noah did it. Anything is possible with Jehoopla's* help
If Jehovah is a perfect God then why did he create Dinosaurs just to then turn around and have them destroyed not once but several times? Did God really need an eraser on his creation pencil?
Dinosaurs were created to tidy the earth before mans arrival, just think of them as the gardeners! Did you know soil is dinosaur poop?
Why would a Loving God create Parasites that kill people everyday? Why would he create viruses?
The original purpose of these animals was to help humans, maybe even to keep them living forever! Because we are sinful nothing works properly.Viruses are an extension of Adam's sin.
Why would he create animals designed to rip flesh from bones if his purpose was for them to eat grass and be completely tranquil and peaceful with everyone.
If Dinosaurs were the gardeners, then carnivores are the cleaners. Carnivorous animals will eat the dead bodies of animals in System 2.0
Why do we see an ecosystem that strikes a perfect balance with all living things via predator or prey food chain system?
It strikes a perfect balance because Jahuba edited the food chain system after the Flood. What else would you expect from God other than perfection?
We now know that we are all related by our DNA. If we were individually created by god should not every DNA pattern be unique in everyway with no relation to any other creature? Yet we see that certian parts of our DNA are simply switches that have been turned off or discarded because we no longer needed them.
An artist is known by his style, and his signature. Though each painting is unique, it follows a similar pattern. To be sure, DNA is the brush our loving designer used when creating all life.
If birds didn't come from dino's then how the hell did scientists recently manage to manipulate genes found in chickens that are also found in Raptors to give them teeth?
*ahem* You'll have to wait on Jobo for that one.
If we are supposed to live forever then why have scientists found that the sun has a finite amount of expendable energy before it super nova's and destroys the solar system?
Maybe our sun is different. You're not God, you don't know!
If we are supposed to live forever why is it known that the Andromedia and Milkyway Galaxy will eventually murge there by destroying everything and then rebirthing into a new Galaxy?
Actually I have to correct you on this one. The Andromeda - Milky Way collision wouldn't destroy our planet, nor our solar system.
