I like to focus on falsifiable claims since unfalsifiable ones would have us talking in circles.
For example if we add up all the dates and chronology of biblical people and events we end up with a claim of earth is around 6000 years old.
What proof do you have that the earth is even remotely that young?
Second falsifiable claim is Noah's global flood that bible claims. Which would be some 4359 years ago. Show me physical proof of global (not regional) flood happened. Records from different civilizations that all line up perfectly
Thirdly bible would have us believe that Noah, his 3 sons and their wives essentially 8 people repopulated the entire planet some 4359 years ago.
How did 8 people repopulate the entire human race with such a wide variety of genetic make up that we have today? I want you walk me through this bilogicaly. The amount of incest and inbreeding alone would turn the entire human gene pool into mutants. Also incest is forbidden according to the bible. So thats a contradiction in of itself. (Thats not even bring up Adam and Eve conundrum)
https://en.wikipedia.org/wiki/Inbreedinghttps://imgur.com/ltisTZW.jpegI don't know how old the Earth is. Whether the Earth is 6,000 Years old or Millions of Years old, I don't know. That's not my area of expertise. The way I see it, the age of the Earth has absolutely no bearing in my decision whether to steal that loaf of bread or not. I'm sure you've heard that Christians believe that the Earth is 6,000 Years old. My answer to that question is don't know, don't care.

God placed the Rainbow in the sky as a sign of the covenant between God and Man and all living creatures that God will never flood the entire Earth again.
Other than that, the answersingenesis domain argue that oil came about because of the global flood. You can skim those articles here:

As for the repopulation we need to read Genesis Chapter 10.
10 This is the account of Shem, Ham and Japheth, Noah’s sons, who themselves had sons after the flood.
The Japhethites
2 The sons of Japheth:
Gomer, Magog, Madai, Javan, Tubal, Meshek and Tiras.
3 The sons of Gomer:
Ashkenaz, Riphath and Togarmah.
4 The sons of Javan:
Elishah, Tarshish, the Kittites and the Rodanites. 5 (From these the maritime peoples spread out into their territories by their clans within their nations, each with its own language.)
The Hamites
6 The sons of Ham:
Cush, Egypt, Put and Canaan.
7 The sons of Cush:
Seba, Havilah, Sabtah, Raamah and Sabteka.
The sons of Raamah:
Sheba and Dedan.
8 Cush was the father of Nimrod, who became a mighty warrior on the earth. 9 He was a mighty hunter before the Lord; that is why it is said, “Like Nimrod, a mighty hunter before the Lord.” 10 The first centers of his kingdom were Babylon, Uruk, Akkad and Kalneh, in Shinar. 11 From that land he went to Assyria, where he built Nineveh, Rehoboth Ir, Calah 12 and Resen, which is between Nineveh and Calah—which is the great city.
13 Egypt was the father of
the Ludites, Anamites, Lehabites, Naphtuhites, 14 Pathrusites, Kasluhites (from whom the Philistines came) and Caphtorites.
15 Canaan was the father of
Sidon his firstborn, and of the Hittites, 16 Jebusites, Amorites, Girgashites, 17 Hivites, Arkites, Sinites, 18 Arvadites, Zemarites and Hamathites.
Later the Canaanite clans scattered 19 and the borders of Canaan reached from Sidon toward Gerar as far as Gaza, and then toward Sodom, Gomorrah, Admah and Zeboyim, as far as Lasha.
20 These are the sons of Ham by their clans and languages, in their territories and nations.
The Semites
21 Sons were also born to Shem, whose older brother was Japheth; Shem was the ancestor of all the sons of Eber.
22 The sons of Shem:
Elam, Ashur, Arphaxad, Lud and Aram.
23 The sons of Aram:
Uz, Hul, Gether and Meshek.
24 Arphaxad was the father of Shelah,
and Shelah the father of Eber.
25 Two sons were born to Eber:
One was named Peleg, because in his time the earth was divided; his brother was named Joktan.
26 Joktan was the father of
Almodad, Sheleph, Hazarmaveth, Jerah, 27 Hadoram, Uzal, Diklah, 28 Obal, Abimael, Sheba, 29 Ophir, Havilah and Jobab. All these were sons of Joktan.
30 The region where they lived stretched from Mesha toward Sephar, in the eastern hill country.
31 These are the sons of Shem by their clans and languages, in their territories and nations.
32 These are the clans of Noah’s sons, according to their lines of descent, within their nations. From these the nations spread out over the earth after the flood.

As for the wide variety of genetic make up we have today I don't know biologically how that happened as that is not my area of expertise.
All I can say is that most likely happened due to the Tower of Babel when they were all scattered over the face of the whole Earth.
Genesis 11:1-8
11 Now the whole world had one language and a common speech. 2 As people moved eastward, they found a plain in Shinar and settled there.
3 They said to each other, “Come, let’s make bricks and bake them thoroughly.” They used brick instead of stone, and tar for mortar. 4 Then they said, “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves; otherwise we will be scattered over the face of the whole earth.”
5 But the Lord came down to see the city and the tower the people were building. 6 The Lord said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them. 7 Come, let us go down and confuse their language so they will not understand each other.”
8 So the Lord scattered them from there over all the earth, and they stopped building the city. 9 That is why it was called Babel—because there the Lord confused the language of the whole world. From there the Lord scattered them over the face of the whole earth.
