Vatican announces stance on Big Bang Theory (Not the show)

Exactly. And the universe went through an extended period of total absence of light for millions of years after the big bang.

Were you around for the first few million years... No, then you have absolutely no idea.

Btw, some animals can see ultraviolet light, others can see infrared. For an explosion of the magnitude we're talking, there would have been a massive energy release across the electronic spectrum. That would have generated a lot of light mostly upper band of the EM spectrum, but would have also been seen in the form of visible light as well.

Microwave Radiation if I recall is a long wavelength part of the EM spectrum, Radio Waves if I recall have a longer wavelength, but infrared if I remember correctly has a shorter wavelength. The thing you haven't taken into account is RED SHIFT as well as how long ago the Big Bang supposedly occurred. A lot of the energy from the event would have dissapated, the longer wavelength results still seen would be the result of RED SHIFT causing us to notice the "echo" of the Big Bang at a longer wavelength than what it actually was additionally, longer wavelength emissions tend to be harder to disrupt or block out.

When you become less ignorant on the nature of radiation and the current perceptions of the development of the universe subsequent to the big bang you will qualify for an answer.

No. Technically, light is a form of electromagnetic radiation. That's not the same thing.

A photon is a photon. Photons differ from each other only in frequency which is to say energy.

E = h*f where E is energy, h is Planck's constant and f is frequency

The entropy of the cosmos (the cosmos is a closed thermodynamic system) is increasing which means at one time the entropy of the cosmos was much less than it is now. That taken with the red shift indicates the cosmos used to be much more compact than it is now.

Well, if I am unqualified, then you are even less qualified. Astronomy is one of my interests, further I have taken Astronomy courses so I am qualified to comment on the topic.

A photon will behave as a particle and as a wave. The wavelength on the EM spectrum determines whether or not it is visible or not, what color it is, etc. The fact we are travelling away from something will change the observed wavelength. Furthermore, if it was only microwave radiation generated during the big bang the results would have been rather miniscule. Microwave radiation is nonionizing and non-nuclear.

The Big Bang is theorized to have produced massive amounts of matter and antimatter (with more matter produced), a lot of that would annihilate each other. A matter/antimatter reaction produces gamma radiation bursts which would react with surrounding matter.

Heck the argument everything was cooled down doesn't even fly in the early universe because of the massive amount of energy that had to have been released in the Big Bang. Early stars were additionally theorized to be collosal to sizes where they could blow themselves apart. In short, the early Universe is supposed to have been a very violent place and it would have been a hell of a light show.

You make a fundamental error here in the transition from your third to your fourth sentence.

We perceive the light reaching us as having been redshifted, but the source of that light is not shifted at all. The whole reason that we can understand the speed of recession is that we can measure the difference between the light that we see and light that was emitted, knowing the frequencies of light emitted from the reactions taking place within stars.

Now, we know that our perception of light when the wavelength is lengthened by recession causes it to shift to the red (lower frequency, longer wavelength) end of the spectrum. But as we know, the farther a body is away from us, the greater the shift. As distance becomes greater, speed becomes greater, and the shift moves successively from the red end of the visible spectrum, into the infrared, and then into microwave.

The energy that was generated at the Hubble radius was not only microwave energy. But it is receding so fast that the wavelengths reaching us are so elongated as to fall within the microwave band.
