Yes, Yes, billions was too much time I meant to say millions. But on the|
other hand billions of years would not have made that much difference in the
distance of the earth from the sun. but our axis does rotate slightly off
axis on a cycle of 36,000 years causing a fairly regular ice age.

Actually a simple experiment which can naturally choose over a short period
of time is given in many basic texts on the subject....that is .......
the dandylions in your lawn eventually only flower on short peduncles
because the mower keeps cutting off the ones with long peduncles. Also the
amount of time that science has 'kept up with things' is really no time at
all. A few hundred years in absolutly nothing in the time span of

Three thousand years is less than a blink of an eye.

Some designs are so "perfect" or adaptable that they survive the test of
time. You forgot the cockroach.

We KNOW that this is simply not true. The proof is in the fossil record.
What is meant by "Always around" When is "always"? LIke before the earth was
here they were floating around in space?

Probably a very accurate statement
Not flaming just discussing,
