Okay, I'll bite. ;)
But just one more time.
You're again confusing abiogenesis and evolution. Life did not evolve into existence, it came into being by random chance in specific areas that had specific conditions, according to 'secular' theories. THEN, and ONLY then did evolution start. The actual process of abiogenesis was very short, it starts the moment before the first lifeform was made and ended the moment it was made. So like, maybe minutes or hours at most compared to thousands or millions of years. What you're thinking of is either the billions of years required to evolve from the first lifeform to humans, or the billions of years required to go from the big bang to the earth forming and abiogenesis occuring.
And I did say it wasn't the
main threat. The main threat is the conjecture that the universe is 6-10k years old is completely unsupported. There are dozens upon dozens of dating methods, one of which is Einstein's theory of relativity itself.
This includes Carbon-14 dating, Urianium-Lead Dating, Potassium-Argon Dating, Rubidium-Strontium dating, Cepheid Star Dating, Cosmological Redshift dating, and so on and so on. I could go into detail explaining them all but I think the most simple one to explain is Cepheid Star Dating, so I'll try that one.
There are many kinds of stars that we can see, and one of them is called a Cepheid variable. It's a star that pulsates rapidly. They've been extensively studied and they're very easy to spot, even from an incredible distance away. It also happens that there's a direct relationship between their pulsing and their intensity/brightness.
[1]There's also a very direct relationship between the distance to an object and its brightness:

Where B is the brightness and D is the distance to the object.
Since we can easily observe how they pulse, and we know the relationship between pulsing and brightness, we can determine what the original brightness is. We now know 2 out of the 3 variables and can solve for D:

Now when we actually apply this formula to say, find the distance from here to the Andromeda galaxy, we get a distance of around 2.5 million light years. Since a light year is the distance light travels in a year, it takes 2.5 million years for the light to get here, putting a
lower bound (the universe cannot be younger than this) on the universe of 2.5 million years, which is well over 10,000 years. There are other methods which prove it's even older but they tend to be much more complex because you have to work with the more complex mathematics of general/special relativity.
if we can't explain how life came to be
then the answer to the question "how did life come to be" is
"i don't know"
you shouldnt default to "GOD DID IT" when you come across something unexplained like the origin of the universe or the origin of life or whatever the forget because nobody will beat you up if you say "i dont know"
This exactly. Just because we don't know doesn't imply we "NEED" a creator to explain it. Besides, we know for sure that it can happen naturally, that's the one thing that the miller-yuri experiment did prove. We just don't know the exact process of chemical reactions that led to it.
