Of course, since all evidence points in that direction.

But the ToE states that monkeys didn't evolve from fish...but fish-like creatures.

You do this stuff on purpose don't you?
Ok, fine I should've corrected you on that in your previous post. There, happy now? I didn't correct a mistake you made.
It's still dumb to say that fish evolved from monkeys.

It is not a matter of belief. It is a conclusion based on the evidence.
The evidence shows that there was life in the seas before any life on land. The evidence shows that there is some common fish ancestor(s) that made a transition to land. All amphibians and mammals are descended from those earlier critters.

Anyone so limited that they can only spell a word one way is severely handicapped!

Why bother?
You have shown you have no interest in learning anything.

Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

We could, but you'd probably misrepresent or misinterpret it and ask another stupid question or make a dumb statement. So no, thanks.

We can try.
A short sequence of some of the critters that existed during the transitional phase from water to land would be:
Eusthenopteron
Panderichthys
Tiktaalik
Acanthosega
Ichtheostega
These are all critters that show transitional feature, some traits common to land animals, others common to fish.

If modern-day apes could argue at all, then they could argue that they evolved from human-like creatures - but they'd be wrong. Evolution doesn't have a direction but history does. We can figure out the order that events happened.

Life is like a Hot Wheels car. Sometimes it goes behind the couch and you can't find it.

So would I be right in saying that none of the examples given are actually ancestors of modern day fish?

Since you had asked for examples of fish-like critters I don't see how that question is even relevant.
Big_Al35 in Message 95 asks "Can anyone tell me what a fish-like creature is?"
The examples I listed are critters that have traits common to fish but also traits not seen in modern fish but seen in modern land animals.

Under what silly definition of fish did monkeys not evolve from them? If we're defining 'fish' as synonomous with 'ray-finned fish' then monkeys didn't evolve from fish, but in this case lungfish aren't fish, sharks aren't fish and all manner of fossil fish groups aren't fish.
Of course monkeys evolved from fish. In a different post you asked what a 'fish-like creature' was. It's a creature like a fish. A fish is a scaly, aquatic vertebrate with fins. Monkeys, along with all other land vertebrates, evolved from scaly aquatic vertebrates with fins.

A "fish-like creature" is another fish.
Like Caffeine said, monkeys and humans and modern fish all evolved from ancient fish. If you were to display the evolutionary history of fish as a tree diagram, you would see amphibians, reptiles and mammals forming a single branch sprouting out of the middle of the tree somewhere.
Some fish evolved legs (and eventually arms) from fins; while others evolved more kinds of fins from fins.
By the way, how can we relate this back to the definition of species (which is what we're supposed to be discussing here)?

The issue I am raising here is one of complexity. Dr Adequate argues that he is not more complex than say a lobster. Extrapolating this argument a monkey is not more complex than a fish. However, when I suggest that a fish might have evolved from a monkey you baulk at this idea. You can only see evolution going one way...ie from a fish to a monkey. This suggests to me that a monkey is more complex than a fish. If it wasn't then evolution, which is directionless, should have the capacity to go both ways.
Now if you suggested that a complex creature could evolve into a simpler creature where its very survival depended on it I might understand this. However, if I gave any example of this you would no doubt claim I was raving mad. I see huge holes in the logic being applied.

Only because the evidence shows that it happened the other way around.

Yes, the evidence only shows this.
This suggests to me that a monkey is more complex than a fish. If it wasn't then evolution, which is directionless, should have the capacity to go both ways.
It has, look at whales for example. Land animals "returning" to the sea. Of course, whales aren't fish, but it shows that evolution isn't bound to go in one driection.
Now if you suggested that a complex creature could evolve into a simpler creature where its very survival depended on it I might understand this. However, if I gave any example of this you would no doubt claim I was raving mad. I see huge holes in the logic being applied.
It's not about logic, it's about what the evidence shows. And the evidence shows that there were fish first, and monkeys later, there is no denying this.
