Imagine getting off your backside, learning that "everything from nothing" is just a stupid dishonest slogan, the inflationary cosmology has nothing to do with biological evolution and then learning about the amazing discoveries that the flagellum evolved from the type II secretory system and that if the genes for the flagellum are knocked out, it re-evolves in a matter of days.

❤ Do a RU-vid search for "Molecular machines" And then, while you are seeing these incredibly complex machines that are inside your body right now, ask yourself: Do these unbelievably sophisticated machines and systems, look like they could come into existence all by themselves.. ..Or, do they look like they were designed and created? And, if they DO look like they were designed and created. Maybe there is a reason for that... .

If every living thing we know is made from / by these molecular machines, do these machines ‘evolve’ as well or have they remained the same since the first cell millions of years ago ? Did dinosaur cells have the same molecular machines ? Or did dinosaur molecular machines look different and evolve to the become the ones that exist today ? It seems that the machines or ‘code language’ Is the same , but the commands / coding produces different living things ?

If you cannot accept miracles that are not designed, you must accept the miracle of the existence of a designer. Doesn't the existence of the designer of such miracles need to explain its origin? Isn't its existence ingenious? Isn't it the result of wisdom? Then there must be a designer above the designer. Unless wisdom comes out of thin air. This assumption is even more bizarre than the ingenuity of life coming from billions of years of evolution.

What's really insane is that it's got a transmission for when it needs more torque and it can even go in reverse. And it's literally powered by protons. There's a TON of crap like this. The sliding clamp made my jaw hit the floor. Mechanical pumps, copy machines (with the ability to reverse and correct errors), and a no-$hit power plant. I can't believe that we've actually achieved the ability to see living cells on a molecular level in my lifetime - and found very clearly engineered, precision workshops manned and operated by a plethora of specialist robots. If we keep improving our ability to see, I hope they find the instructions and the warrantee. Mine is quite banged up and barely operational. I probably missed that I'm supposed to lubricate a few parts and the rust is building up on the gears. I keep taking it to various mechanics, but I'm starting to doubt that they know what they're doing.

I love how RNA leads to the creation of 3D structures which can then do useful things and further combine into more useful things. It’s like a 3D Turing machine but where the output has physical functionality so is infinitely more useful. It’s like the ultimate programming language and computer combined into a single complex process. It’s stunning.

This is obviously a created mechanism that never could happen by evolutionary happenstance. Evolution is saying given billions or millions of years if a tornado continually was rotating over a junkyard eventually you would have a fully functioning car. If Bill Gates used millions of chimpanzees banging away on keyboards for millions of PS of years then eventually you would get Microsoft Windows. Things in nature break down (law of entropy), they don’t come together in intelligent design. Darwin knew nothing of the complexities of living cells or DNA. You have to be “educated” to not believe in God and then you become a fool, since the creation screams the truth of a creator.
@notsoclearsky
@notsoclearsky 4 месяца назад
The difference between a tornado rotating for billions of years/monkey typing and evolution is that, a tornado starts every next step from complete randomness, that is, all steps are erased after every step. Life is different, once a self replicating chemical reaction occurs, next chemical reaction uses the by products of the first reaction, over time, you have building blocks of life and you don't start over every step like with the tornado. Its okay to believe in god, but it's certainly not okay to present false examples to support your claims. Let me ask you something, the scientific advancements have given us things that religions promised us, aka, miracles of light in darkness (bulb), instantly sending your voice to thousands of kilometres away (voice calls), a magic mirror (a video call), going to the moon (Apollo), just to name a few. But on the other hand, the pope and religious preachers are still preaching that the world will end in next 10 years for the past thousands of years. What makes you still believe in god instead of scientific advancements?
