Will somebody please tell me how birds came to be?
Birds came to be the same way other organisms came to be as they are today, through the process of random mutation and natural selection. If God simply created birds as they are today then how does one explain the fossils records of early birds such as Archyoptrix? What drove bird evolution was evolution IMO.

changes in gravity ???

In the cases of the ostrich, moa, and other larger flightless birds, in the ones which survived the changes in gravity which killed off the larger dinosaurs, they had gotten too heavy to fly..
Umm...I thought this changes in gravity theory was previously discussed in another thread and the consensus was that it was NOT a scientific verifiable fact. *edit typos.

Humans never bred chickens to "stay put:. We bred them to lay eggs and taste good Until very recently they were never kept in cages....
The byproduct of breeding chickens to taste good as you say increased the size of the birds which in turn minimized they're ability to fly, which was advantageous in keeping these birds from roaming to far. Edit to add: How do you explain humans ability to select for traits in domesticated birds; if natural selection and random mutation in birds is false then how is it humans can drive bird evolution artificially? If it is possible to select traits in breeding birds then it is possible for the process to take place naturally as well, IMO. If you do not believe that the TOE is valid then you are neglecting knowlege simply because it does not agree with your religious beliefs . Not because it is not an accurate model. This is what is known as being dogmatic Red Wolf.

This thread is beginning to turn foul
This thread is beginning to look alot like redwolfs 'different gravity ' thread..all these assertions and nothing to back it up. Why should anyone think that natural selection and random mutation was not what drove bird evolution? Sure there are some creationist sites out there that preport the same (how could birds have adapted if there are examples of birds that do not fly.) If its true of birds then the whole theory of evolution must be false. Well it is not true of birds, ancient birds have left fossilized remains. How does a creationist explain the fossil record. How does a creationist explain the Galapagos finch data of how finches have evolved? Adaptation of organisms through natural selection is such a elegant model . Anyone who cares to learn the basics of evolution can attest to it's common sense premises. Why is it so hard to understand? Chickens do not fly well...Ostrichs do not fly at all, and neither do Penguins. If there is a niche to exploit then nature has found a way to allow organisms to fill that niche. It is really that simple. If there is no advantage to change then the organism remains the same.. this is true of many extant creatures such as cockroaches, coelocanth fish, natalis, turtles, and thousands of other creatures that were contemporary with dinosaurs. This is a no brainer. Either present some compelling data to shed some validity to your premise or lets move on and agree to disagree.

LOL. I think that the whole topic has been exhausted.
