Redleghunter, let's talk a little about the dating of Acts.
We don't know when Acts was written. It was probably after 63 AD, since it records the trial of Paul, and must have been before about 150 AD, which is the first the book is clearly quoted by others. So that gives us a range of about 60 AD - 150 AD that we can be confident in. If we try to narrow it down more than that, there is a lot of guesswork.
Also the book of Acts most likely was edited in stages. So hypothetically somebody may have written a text with 40% of the current Acts in say 55 AD, which got edited in say 64 AD and 79 AD, and then got merged with a document from say 63 AD in 84 AD, and then edited again in say 95 AD and again in say 120 AD, giving us the modern version of Acts. If that happened, what would be the correct answer for the date of the writing of Acts? Analysis of the internal text of Acts might find hints for a wide range of dates.
So nobody really knows the range of dates between the first proto-Acts to a document close to today's Acts. Beyond saying it was written between 60 AD and 150 AD, we can't be too dogmatic.
Can I suggest that you read some of the reasons people have given for a late date? See, for instance,
When and Why was Acts Written?
The knowledge of the fall of Jerusalem is indeed a valid reason for dating all the gospels and Acts after 70 AD. But that is probably a complex topic for another thread.
Earlier writings would also be subject to error. And later writings could actually be considered quite accurate if they had clearly identified sources, historical and archeological backing of the events themselves, and multiple documents attesting to the events. But what we have is documents that could well be late, with no clear mention of the sources.
Sorry, the late dates of the documents is not a conspiracy theory. Read for instance the link I provided above.
