If I wrote a history of the Roman Empire, would future generations say....?

Question

1. That it could not possibly be accurate because these events occurred long before my book was written and I was not even there to witness them?
2. That it could not possibly be a true account because other earlier cultures have similar accounts and surely I copied these and put my own interpretation on them?
3. That the history of the Roman Empire has been corrupted by so many different accounts and translations?

Answer 1

Yes, especially if they didn't want to believe that the Roman Empire existed.

Answer 2

Guess it depends how good your book is.
