How did we cut our hair and nails without metal objects? Metallurgy, like speech and writing are probably available to man since the fall, around 6000 years ago and certainly since the flood approximately 4,400 years ago.

Good point.

The Bronze Age is a historical period lasting from approximately 3300 to 1200 BC. It is characterized by the use of bronze, the use of writing in some areas, and other features of early urban civilization. The Bronze Age is the middle principal period of the three-age system, between the Stone and Iron Ages.^[1] This system was proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition.
The periodisation of the Bronze Age is generally ended with the Late Bronze Age collapse, a time of widespread societal collapse between c. 1200 and 1150 BC. This collapse affected a large area of the Eastern Mediterranean, including North Africa and Southeast Europe, as well as the Near East, in particular Egypt, eastern Libya, the Balkans, the Aegean, Anatolia, and the Caucasus. It was sudden, violent, and culturally disruptive for many Bronze Age civilizations, and it brought a sharp economic decline to regional powers, most notably ushering in the Greek Dark Ages.
An ancient civilization is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from producing areas elsewhere.
Bronze Age civilizations gained a technological advantage due to bronze's harder and more durable properties than other metals available at the time. While terrestrial iron is naturally abundant, the higher temperature required for smelting, 1,250 °C (2,280 °F), in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end of the second millennium BC. Tin's lower melting point of 232 °C (450 °F) and copper's relatively moderate melting point of 1,085 °C (1,985 °F) placed both these metals within the capabilities of Neolithic pottery kilns, which date back to 6,000 BC and were able to produce temperatures of at least 900 °C (1,650 °F).^[2] Copper and tin ores are rare since there were no tin bronzes in West Asia before trading in bronze began in the 3rd millennium BC.

The idea that the Earth is just a seashell bobbing around in an infinite ocean of "outer space" is such nonsense. And it's calculated to weaken faith in God and religion, and bolster the atheistic Big Bang model of cosmology.

At the end of the Apocalypse, God says He will create "a new heaven and a new earth". Why? If you have ALL THAT REAL ESTATE, why waste your time? (with all due respect). I mean seriously -- according to science, there HAS to be an earth-like, or even BETTER than earth-like, planet out there somewhere in the Cosmos, perhaps too far away for humans to reach. EVEN IF there is no life out there besides earth (which no "official science" textbook would ever suggest). Why wouldn't God just move his Elect instantly to another great planet he made? Why even bother with this ol' Earth? Just toss it into the sun, and move on with Your (infinite) life.

And does that new heaven and new earth include a new sun? Because it would be a shame for the New Jerusalem to get swallowed up by a red giant Sun, golden streets and all!

I always used to think deep down, "Can I pass on that new heaven/earth? I'd really rather like to check out those many cool exoplanets You created millions of light years away, with my new glorified body, if You don't mind that is..."

See the problem with trying to bring atheistic religion's nonsense into the Catholic Faith? It really doesn't work.

See, like everything else, the Bible and religion seems quite silly when you try to fit it into the atheistic context of Carl Sagan's "The Cosmos", with billions of galaxies, planets, etc. And besides, you also would expect countless other civilizations, which they are ALSO programming us to believe.

Our Lord ascended into heaven. Which direction did he actually exit the ball Earth? Sideways? Upside down?
Hell is supposed to be DOWN. What, into the center of the earth? And if they go too deep into hell, they emerge in China on the other side of the "planet"? Ridiculous.

Joshua made the sun stand still. It didn't say he stopped the earth turning. And if he DID, wouldn't everything be destroyed by the sudden stop? The wind and G-forces would have been cataclysmic, and wiped out all life on earth, according to science. But Scripture says clearly: the sun stood still. I would rather take that literally, than bend over backwards to find excuses and convoluted explanations, all to defend some atheist's "billiard ball cosmos" worldview.

They have all those cross-section cutaway views of the earth's layers and core. Guess how far they've drilled down. Anybody? Answer: 7.6 miles. That's it. All the rest of that they're pulling completely out of their butt. It's not science, it's human "faith" in some bizarre science cult.

If heaven is ABOVE the firmament than Our Lord ascending UPWARDS makes sense. But what is heaven in the globe model? Outer space? No heaven there. Sorry, kids. Just a harsh, cruel vacuum. I guess mommy and daddy deceived you about the nature of the universe and world you live in.

So you see, you HAVE to call bullshit on either A) the Catholic Faith or B) the heliocentric/globe model with Carl Sagan, Einstein, Steven Hawking, Neil DeGrasse Tyson, and all the rest of those clowns. NASA can't be where the truth is; they lie too much. They've been caught in more lies and deceptions than I can count. WHY are they lying?

I choose Holy Scripture, God, and the Catholic religion. I encourage you all to do the same. But it is difficult to keep one foot in each camp. Eventually, you pick a side. May you pick the right side.

Having your WHOLE self, your life, your beliefs, your hopes and dreams ALL in one side, all in one worldview, makes for the most stability and chance of salvation. There is no need, nor is it wise, to attempt to "square the circle" and reconcile two vastly different, contradictory, competing worldviews.

Absolutely. Been a flat-earther since 2015 and have been pretty open about my views. Strangely (and maybe fortunately), less people seem to balk over it these days 

Ok i am confused.  How are the sky and space not the same space? We look in to the sky and we see stars.  A random person looks into the sky and is able to take pictures of strange things that we are told are nebulas or galaxies or planets.  But there is a deception?  What is the deception?

"Planets" are also stars. Says so In Scripture somewhere. Have you ever seen a random star through a telescope? They look crazier than "planets", like a rave in Heaven.
