I usually in the following first let him speak, see video, then say where I disagree on some:
Origins: What's the Biblical Age of the Earth?

To explain the chronology I use, it's by St. Jerome, and based on a non-standard LXX, which has a Samaritan identic Genesis 11.
I thank Jonathan Sarfati for pointing out, there are manuscripts of Luke 3 that do not have the Second Cainan.
8:44 Jephtha must have meant "at least 300 years" or otherwise there were intermediate periods when Heshbon was not in Israelite lands. Jephtha is speaking c. 380 / 390 years after Exodus ended.
I started with Joshua starting 40 years after the Exodus and went through chronological statement after chronological statement with an estimate for how long Joshua lived after taking Jericho.
9:51 230, 205, according to the LXX.
14:30 They were not inside the garden of Eden, which need not have been tropical, and as Adam and Cain tilled the earth, this is presumable evidence they were in the temperate zone, so they could do agriculture.
Babel to Exodus and arguably even Flood to Exodus would definitely have been within the temperate zone, so 12 lunar months is out.
Given that Genesis 1 for day four actually says, in an intro, before specifying sun, moon and stars, that the lights are created as signs, on whatever place Adam was on a globe earth, he could have checked the visibility or invisibility of certain stars.
Orion is most visible in the evening sky from January to April,[3] winter in the Northern Hemisphere, and summer in the Southern Hemisphere
In the period May–July (summer in the Northern Hemisphere, winter in the Southern Hemisphere), Orion is in the daytime sky and thus invisible at most latitudes
12:28 Robert Carter had his 37th birthday later in 2005, so was born in 1978, ten years younger than me.
His GG-Grandfather was born in 1859. That's 9 years after an ancestor of mine, but he was only my G-Grandfather.
20:23 Terah was 70 when Abraham was born.
And from thence, after his father was dead, he removed him into this land, wherein you now dwell.
St. Stephen, like some Jews, means, when his father Terah fell into idolatry. Not when he physically died.
Alternative, St. Stephen means when Abraham's spiritual father had died, like if that was Sarug, let's say, he died when Abraham was 50, so Abraham waited 25 years.
21:23 The clock starts with Abraham:
Now this I say, that the testament which was confirmed by God, the law which was made after four hundred and thirty years, doth not disannul, to make the promise of no effect.
[Galatians 3:17]
Two solutions.
a) the original text is in Exodus 12 (not 4!) according to the LXX:
And the sojourning of the children of Israel, while they sojourned in the land of Egypt and the land of Chanaan, [was] four hundred and thirty years.
ἡ δὲ κατοίκησις τῶν υἱῶν ᾿Ισραήλ, ἣν κατῴκησαν ἐν γῇ Αἰγύπτῳ καὶ ἐν γῇ Χαναάν, ἔτη τετρακόσια τριάκοντα.
b) this is not the original actual text, but the original meaning, supplemented in the LXX translation, as Chanaan in Abraham's time depended on Egypt. So, being in Canaan technically meant being in Egypt.
