re: No matter what direction we point a telescope, we always look toward the Big Bang - why?

The hardest thing to conceptualize about the big bang is that it happened everywhere all at once. It's hard to comprehend the size and scale of it when we try to fit it in the context of explosions we observe on earth.

The farther away you look, the older what you see is. So if you are looking billions of light years away in any direction, you are looking at light that is billions of years old.
Allegedly.

Only if you define everything as everything in the reach or influence of the big bang.
An explosion is an explosion. It's just a matter of scale. How do you apply that to what we're observing?

The earth is the center of the universe, so is everywhere else. Duh.

Because they’re always running reruns. Sheldon isn’t that funny. Stop it already.

According to the standard models there was no space and time before the Big Bang. There was not even a "before" to speak of. So, the Big Bang was very different from any explosion we are accustomed to and it does not need to have a central point.
That sounds an awful lot like some “we don’t know but want to claim we do” bullshite

I believe we call that the "universe".

The big bang was a universal explosion. Trying to fit it in the box of it being just another explosion really limits the ability to describe what (theoretically) happened.

Because you are thinking of the Big Bang as an explosion IN space, and material moves away from it.
The Big Bang was an explosion OF space. Where the mass within increases the spaces between each other.
This is also why Webb telescope finds its value. Over a long enough distance, the expansion of space begins to have an effect on the movement of light, causing a Doppler effect (how a car sounds different when it’s coming towards you vs when it’s moving away). This effect shifts light more to the red end of the spectrum, turning visible light (what Hubble sees) to infrared light (what Webb sees). This is why Webb is citied as being able to see further than Hubble could.
The long range stuff doesn’t appear in the wavelengths Hubble can see.

Because that’s how God made it
There is no principled reason for any religious person to turn away from the physical sciences. If God made everything and placed it here for us to discover and be impressed, how can a Godly person turn away from it or deny its existence? If you believe in creation, that should give you a greater incentive to witness and try to understand what was created for you.
When given a wrapped gift, the only thing to do is open it.

That's how theories work. There's something you don't know and you postulate how based on information you have currently. From there you search for evidence to support it or disprove it. Not sure why there's such animosity toward that process nowadays.
Is it bullshite? Time will tell. For now, it's the theory with the best evidence to support it.

Right. It's still a limited set. It assumes without evidence that the universe is everything there is and there is nothing outside it.
My point is this:

Does not explain why a limited envelope of matter surrounds us apparently equally in all directions.
Models of the big bang generally show either a shotgun blast or a central explosion going off in opposing directions.

It is easier and more logical to believe in God, than the Big Bang.
Yes, throwing your hands up in the air and just saying, "magic," is always easier. The magic man did it, and his ways are mysterious. That's literally always the easiest answer.

A 13 billion year old universe with evolution negates original sin and Christ's redemption. It makes the Bible a lie. It is just as reasonable to assume that science is biased by a need to disprove God and the Bible, since, you know, since it's been said over and over.

Say the United States and China each had a “James Webb” kind of telescope on the ground. We both point them in opposite directions towards a patch of the sky at the same time. If both telescopes could see back 13.8 billion years, they’d both see the Big Bang.
Like a perspective drawing from a flat earth, now we’ve done it.

What religious are turning away from science. Its because of the Church we have basis of the scientific methods we use today-- the only people rejecting science today are the climatologists.

Lol, no. That’s a strawman advanced by biblical literalists who feel attacked by advancing knowledge. Science literally doesn’t give a shite about god, since by definition supernatural shite is not testable.

Do we know in which direction we are heading? Can we know and look back at the spot of the proposed singularity?
Is the light emitted from stars that are farther down the path we are headed different in some manner from the light emitted from stars that trail us in our path?

It's not. You're lying. But if you want to siderail this into a science vs the Bible debate go for it. You're being a douche. I have approached the topic under the assumptions provided and responded rationally. Maybe take your hobby horse elsewhere.
