It has been the same Almighty sending Messengers and Messages to all humanity,but each time a book is revealed(and yes I do believe in the original Bible being the word of the Almighty,and I also believe in the original Torah being revealed by the Almighty).
-each time revelations are sent, a group of people believes,some turn their backs to the revelation,which would mean there will be at least two groups of people (or could even become two different religions).
And then there will be those who form their own ideas from the revelation and this in turn may become a new religion,that makes it three different religion at least per revelation.
Not to mention those who break away from all of these groups and form their own beliefs mixed/not mixed with older beliefs before the revelation of that time(maybe follow the revelations of ages past).
And I do believe that each time a chosen Messenger is sent,some follow him or they reject him or they start worshipping him instead of the One Almighty.
Now years since the revelation, some are still following the original,while others have made changes as per their own thoughts,while others are lost in between,some reject all of these and form their own opinions on how life is to be lived.
The best thing is to do a comparison of all three monotheistic faiths books(as you already do believe in an Almighty),where you will be able to find the similarities and differences.
You may see what I said about the revelations from being the same source when you see the similarities in the books and the commands too.
