Regarding the hilited area, where did you get the idea that fish were classed as part of tetrapoda (meaning "four footed")?
I might be wrong, but I think he meant the minus to mean "vertebrata" which are not "tetrapoda".
ETA: beaten to it...

For example, according to evolution, the fossil record should show a progression of life forms from the simplest to the most complex.
Ignoring the rest of what was wrong with your post, this statement is particularly untrue. Evolution doesn't favor complexity, but the ability to reproduce. There are many cases where evolution has resulted in a simpler life-form, as that was what worked best in the environment. Take a look at many parasites for excellent examples.

You are right. What does invalidate evolution is the lack of physical evidence. Instead, the evidence proves creation. For example, according to evolution, the fossil record should show a progression of life forms from the simplest to the most complex. It doesn't. Instead life forms appear suddenly and perfectly adapted to their environment with no connection to any former life forms.

No.
Why do you guys keep saying things that are so obviously false ? Shouldn't you, I don't know, educate yourself and understand evolution before you start arguing against it ?
But not exactly. Diversificaiton implies some organisms will become more complex but the trend isn't towards complexity.Life starting as its most simple, the diversification will display a trend with progressively more complex organisms evolving, which is, once again, actually the very trend we observe...

You have already been told once that this is wrong, and why it's wrong. It is dishonest to simply repeat it as if it had only just occurred to you for the first time (and especially when we know it never occurred to you at all - you are just cutting and pasting whatever your creationist sources tell you.)What does invalidate evolution is the lack of physical evidence.

Well, actually, that is an implication of the abiogenesis theory.
If life started through natural means, it makes perfect sense that it'd start as its most basic and, from there, evolve, among other things, toward more complexity...

Careful, now. Obviously the earliest lifeforms were simple, and complexity came later. But it doesn't follow that evolution results in more complex lifeforms always.

How fast is "suddenly"? Crabs, for example, took millions of years to evolve after lobsters arose.Instead life forms appear suddenly and perfectly adapted to their environment with no connection to any former life forms.

Yes it is. Here's a thought experiment - imagine we have a scale that measures complexity, with 1 being the simplest possible organism and 10 being the most complex possible organism. Assuming there are no pressures acting specifically on complexity, so inherent trend towards either complexity or simplicity, you will end up with a random walk around the scale for each evolutionary path. When life starts with abiogenesis, all organisms are at 1. As the random walks progress, organisms spread out along the scale. After one step, some will be at 1, some at 2. After two steps, some will still be at 1, some at 2, some at 3. Of course, some of those at 1 will be organisms that have become simpler again.
Carrying on doing that a large number of times and you end up with an even spread across the whole scale. It will be a dynamic equilibrium with the complexity of any individual line changing all the time, but with the average complexity of the system remaining constant (assuming a large enough sample). At every point until the steady state is reached, the mean complexity will have increased, even though the complexity for any given line can increase or decrease.
Now, this assumes that there is actually such a thing as "maximum possible complexity". If that's not actually the case, then the steady state will never be reached, and overall complexity will always increase. While I doubt there is a solid limit, things like energy costs and redundancy requirements will likely act to limit increases in complexity, so things should be closer to the limited scale than an open one.
I'm pretty sure this is all Simon39759 is saying. Not that every organism will always become more complex, but simply that if you start off with only the simplest possible cases existing, there will inevitably be an overall trend of increasing complexity, regardless of the trend in any individual case.
