I started at:
#1. Sea creatures don't exist (minus the sea monster maybe...)
There is no maybe...
#2. All life headed to land once they got legs; ...
You don't need legs to get to land
#3. Creatures bigger than a 5 storey building once roamed planet
s and terrorized the creatures living alongside them
They still do.
#4. No animal is capable of true flight
Define 'true flight'. I define it as the ability to gain altitude combined with the ability to control direction. SPOOR creatures with the proper parts and abilities can do this, unlike some creatures which can only glide slowly downward towards the surface, e.g. humans and some squirrels.
#5. The notion that animals can give birth to live young is nonsense - every creature (even mammals) was hatched from an egg (not referring to the cell)
I don't see your point here. Life, as we know, comes from an egg; either on a cellular level or a macro level. Everything comes from an egg.
#6 Packs can't have more than 4 or 5 animals.
My nest(s) have way more than six(6) but I can only convince three(3) others to follow me.
#7. Flotsam and jetsam doesn't exist
"Flotsam and jetsam" redirects here
: Marine debris, also known as marine litter, is human-created
waste that has deliberately or accidentally become afloat in a lake, sea, ocean or waterway.
#8. Creatures are doomed to stay forever on the continent where they first developed
FALSE: I have terraformed planets and placed colonies in the middle of oceans. I beam down some creatures and the proceed to nest around the planet.
9. Creatures that are smaller than several centimeters don't exist
How do you know? I have yet to see any measure of length standard to be set. In fact, if I can travel from my Home Planet to its Moon in fractions of a second, perhaps these tiny creatures you want to see are nake to the SPOORAN eye. And in Cell stage? How big/small are those guys?
#10. Food was the only gift known to man during the tribal phase
What is this "man" you speak of? Weapons could be a gift, but would you really like to give your tribal neighbors better weapons than you have? What about Fire? Think about it. If you were in a tribal scenario would you really want to trade these monumental discoveries? Maybe you can give them the WHEEL and they can roll over you like yesterday's news.
