There are sources available to answer each and every point of that very lengthy pdf. Materials such as these are age old and have always been around in different forms. Written, plays, stand up comedy and even movies.
The efforts are as old as the Kuffar of Makkah and Madinah during the noble prophet's lifetime till now and most likely the future too.
If anyone wants the truth and concludes "truth" with this fictional novel then no amount of evidence will suffice for them. If anyone wants the truth 'after' reading this book and then study real sources of history, accounts, Qur'aan and Hadeeth then they will find the truth.
The Ulamaa have found this question impossible to answer as a Q&A page on this web site and find it more suitable as a book. In which case many renowned books on the history of the noble prophet with sources and evidences are already available.
I have added this answer on everyone's behalf. I hope it is useful
And Allah knows best
