If we want to talk not about speculation and actual fact i.e meaning what we know for certain, then the following quote sums this up regarding history:
''...real history is available for only the past few thousand years. The beginning of [known] written records... dates from about 2200BC and 3500BC. To keep things in perspective, one should remember that no one can possibly know what happened before there were people to observe and record what happened.'' - Scientific Creationism, Henry Morris, 1985, p.131
Anyone saying history predates this period of documentated history can not know for definate, since they could not observe it. There is no time machine. So if we stick with just the facts, then what we know is that man is only a few thousand years old, supporting Young Earth Creationism.
And we come back to this old chestnut. So presumably you don't accept forensic criminology either? It is the EXACT same thing - using what we can observe now in tandem with established processes to infer what happened.
Why is history (and again, I'm referring to "history" as the particular action of writing down history, not the mere act of existing) the only valid way of establishing with certainty whether someone existed or something happened?
If you never wrote down a single word in your life, nor was there a word ever written about you, then you passed away, would it be reasonable for someone to claim you didn't exist, purely because there was no written record of it?
Would it reasonable to continue do so even in the face of someone else having dug up your skeleton and having obtained your DNA from it, etc?
The other reason for history not being a perfect standard is obvious - people lie, or make up things to explain what they do not understand. Reality can not.
Here's the problem, how does 'pre-history' exist? There is no sense behind this concept.
This is no problem in the slightest, of course there is sense behind it - because history when properly defined involves
written accounts. If the concept of writing did not exist, then it is quite possible for there to be a pre-historic period. The point is, existence does not necessarily mandate there be a written account of it for
all of it.
The creationist argument would be cultures that appear 'primitive' were simply contemporary to those more sophisticated, and not that everyone evolved from a lower level.
How could they even be so confident about that? By the standards discussed so far, they shouldn't even be sure those cultures existed in the first place, they didn't make a historical record of themselves.
I mean, we'll ignore all those skeletons etc for the time being.
Because it was the first time this sin was committed, the same for the flood. In Genesis it says God would never again send a flood. And this promise remains in tact, since we have not observed another world-covering deluge.
Again, this is conflating the topic with an irrelevant event. God made no such promise regarding Babel.
