I commend your enthusiasm, but your reasoning is a bit flawed:
To understand how flying insects can be larger in warmer areas, one must understand the principles of flight.
First of all, the warmer the air, the greater the lift. Also, the more humid the air, the greater the lift.
It order for an insect to fly in colder, dryer areas, it does in fact have to be LIGHTER.
Thus, smaller insects will live in cold, dry places and large insects will live in warm, wet places.
Also, rocks are not dated by the presense of radioactive carbon. Some other form of radioactive decay is required to measure the age of rock strata. Rocks usually don't contain a lot of carbon. Rocks are more silicon based than are organisms.
One might say that carbon lifeforms in the inner Heliosian Solar System are indeed parasites of large, silicon lifeform named "Earth". Earth eats meteors for breakfast and excretes carbon dioxide and other organic and inorganic compounds every once in a while through a number of its many anuses which we humans call "volcanoes".
We, the carbon life parasites of Earth, therefore, manage our lives by internally and industrially consuming Earth's flesh and Planet sh!+.
Remember that next time you sit down in a fine restaurant.
Here's something you should really really consider:
The oldest rock strata on Earth's continents are 4.3 billion years old.
The oldest rock stratat at the bottom of the pacific ocean however, is 200 MILLION years old.
Consider for a moment, that 250 million years ago, 96% OF ALL LIFE on Earth was wiped out by some cataclysmic event that no one has been able to pin point.
Earth also has a moon of a volume that would fill just about all of Earth's oceans.
Earth's moon is considered to be "TOO BIG" to be a "natural formation". Luna would be more at home in a more Jovian planetary system like Jupiter or Saturn, maybe Uranus or Neptune, but it is way too big to actually "belong" to Earth, unless at some point in time, the Moon was in actual fact, part of the Earth, and something massive and watery struck the Earth, filling the oceans with Water and shaking a whole bunch of loosely packed material such as the lunar regolith to separate from Earth's crustal structure.
Also, "something" wipes out tremendous portions of life on Earth ever 26 million years with clockwork-like precision.
Some theorize that the sun passes through a "danger zone" in our local cluster every 30 million years or so, as it rotates around the galaxy. The sun actually moves in three directions:
1) Running away from Andromeda which is out to "get" us.
2) Circling a local region of space.
3) Circling the galactic nucleus.
Others theorize that there is a "Dark Star" which orbits the sun in the opposite direction as the planets.
This "Dark Star" has an orbital period of 3600 +/- years and is likely a sub-brown dwarf. Not quite a planet, not quite a star and not big enough to be considered a "brown dwarf". It's like a really really big Jovian planet that makes its own heat by intense gravitational pressure. Enough heat, possibly, to support life.
The ancients refer to a strange people called the "Anunaki" who visited Earth almost 200,000 years ago and gave rise to human civilization. They used to change rulers every 2,160 years.
The last time any historical evidence of this strange "Dark Star" was reported was in the new testament of the bible, when the Magi from Persia followed this strange object until it "came to rest" over "the place of the King's birth".
Jesus also said, when he "ascended into heaven" that people would see him return the same way he left.
All of this possibly means many things:
1) Very soon, we will be visited by the Anunaki, again.
2) They won't be back until about 3600 AD.
3) Jesus was an alien, or a human/alien hybrid of some sort.
4) In thirteen million years, we're doomed if we don't get the flork off this planet or develop a way do deflect a G&d D&mn mini-star/superjupiter. Supiter?
Believe what you will.
I still say we need $125,000 to build a Sceptre of Infinite Possibility.
