Therefore, it should be of no conflict with science to claim that Adam's size, or man's initial size on earth in general, was in the neighborhood of 90 feet tall, or that the first human-race ever walked on earth was around 90 feet tall, give or take 10 to 20 feet between the creatures' differences in heights as we today have people as tall as 7 feet and as short as 2 feet tall. The reason for this is simply because the planet earth was much smaller than what it is now.
