I don't even know where to begin dissecting that mass of logical contortions.In other words, they aren't exact duplicates. Why would anyone imagine they would be? What you can't deny is that they are very similar, and the feet are almost identical.Well all in fun but...I never saw fort fun Indiana claim he thinks Jurassic park exists.
No one can convince Fort Fun Indiana different. To him birds from dinosaurs is a fact. He thinks the re-engineering of beak and legs will eventually happen or else he has to go back to the drawing board to explain how birds became dinosaurs.
Creation science doesn't think birds macro-evolved from dinosaurs because their lung structure is different and that their leg structure (femur) does not move significantly when they walk or run. They articulate their lower leg structure in order to run. This is so in order for the birds to take air into their lungs. Otherwise, their air-sac lung will collapse with dino legs which has both upper and lower leg motion. This air-sac lung gives them enough lung capacity for flight.
Their leg structure is almost identical:
Comparison of T. rex and emu feet

A T-rex and an emu are not the same size. The photo is deliberately misleading to show the similarity of the foot. You're not looking at the upper leg structure or the femur. They are quite different.

Above is the skeleton of an emu. Follow the lower leg up to the mid-leg and to the femur or upper leg above it. The femur is right above the emu's knee. It does not move as much and this allows for the emu's air-sac lungs to fill with air. If it had an upper leg like the T-Rex, then it would not be able to breathe. Its lungs would collapse. Birds have this unique leg system.
Compare the emu's femur with the T-Rex one. The T-Rex one has a very mobile femur.

I even picked out a small T-Rex skeleton to show how the femur is different and its motion is way different from the emu. There you go. Another case solved by jb.

Is your avatar an exact match to you? I can see you being a whiny child ready to be timed out.
What part of the bird would not be able to breathe do you not get? As for the three fingers, the three fingers on birds aren't the same as the three fingers on theropods. Also, you have a problem in how these theropods grew wings when they didn't have any before.
Finally, it's interesting you changed the T. Rex with an Archaeopteryx without much explanation how it got to be that way. My reply to that is the fossil record shows that birds lived BEFORE the theropods and that they grew up in a parallel timeline. This is the coup de grace for the birds from dinosaurs theory.
BTW, it says "FREE fingers," not "three fingers."
The fossil record does not show that birds lived before theropods. The latter originated about 233 million years ago. Archaeopteryx didn't appear until about 150 millions years ago.
What is your justification for claiming that "birds would not be able to breathe?"
"I have problem in how these theropods grew wings?" How is that any different than explaining how animals grew legs or fingers or teeth or eyes or lungs or tongues? Before birds appeared, theropod dinosaurs already had feathers and arms. The step to wings wasn't that much of a leap.
