is every single thing is predetermined?

An idea stuck to me, it may be old though.

As far as my knowledge of physics is concerned,
We do not have any (basic) event which begins itself i.e. every event(and state) is result of some event which happened in previous state. At those event happed as per rules of nature(or physics).
So nothing is random.. things those seems random are just complex and are just made of lot of events happening together.
In this way whatever event are guiding our thoughts can not be random. those events may be huge in number and may happening very fast but if we choose a single of those that must be due to some previous.

Not going in confusing details..
Every single event in universe is guided by rules of nature. Nothing is random. Nothing is new. Nothing is beginning (after beginning of universe).

So are our thoughts just an illusions to us? Whatever we are doing is predetermined (at beginning of universe)?? my typing this post is predetermined?? you are reading this post, is this predetermined??

May be I messed it up. I will try to clear it queries come up.

Does God Exist

this is probably the most discussed question among the human beings..

My stand is
1.I am not sure
2.At present we(human beings) are unable to explain certain problems(or questions).This means that either "our theories are wrong somewhere" or "we do not know some of the facts and theories" or both.
3.I believe (and i have NO reason for this belief) that some day we will be in a situation when we will explain EVERY THING. And Only in that situation we will be able answer the question asked in this post "Does God exist" .and if it does exist, what it is?.. till then we can keep discussing to make this journey fast.
