There are so many reasons why a God must have been involved in the creation of the universe, that I wouldn't even know where to start! You must have heard all the arguments?
Do you really want me to list them?
I will give a few points here, but these are only based on scientific evidence (which I'm sure you'll find it easier to relate to) I could give various historical arguments, as well as personal arguments which convince me that there is a God.
Each of these points have numerous sub points but I'm not going to list all of them.
For one thing the odds of a stable universe forming at all out of the big bang are incredibly small, and dependent on a number of parameters.
For another the conditions a planet must meet in order to sustain life are extremely tight!
For another the formation of complicated Organic Compounds eg. Proteins, from their elements is an extremely complicated process. While it might be possible for these to form by themselves, the odds of the right conditions occurring for this to happen are also extremely small.
For another thing, it is ludicrous to think the formation of life (or organic beings that have self-awareness, are able to think and reason) from organic compounds, could just happen by itself.
I can't understand how anyone would believe that chemicals can suddenly get clever, and figure out a way of carrying out the processes that the simplest living things do, such as: eat, react, digest, excrete, reproduce, defend itself, move around, sense its environment, sense similar organisms, etc.
And then on top of all of this, over the years these beings begin to refine themselves, they become more advanced, until ultimately, they are so advanced that they can invent, think, reason, feel, experience emotion, comprehend their environment and how and why the world around works.
You surely don't need me to tell you that there is no possible way ALL of this could have happened by itself, by chance.
Sure I believe in evolution to an extent, there are a lot of surprisingly common features between all the mamals for example.
I believe the big bang, or something like it must have happened, to trigger everything we know into existence. But I cannot believe that all this could have happened by itself, without some greater being controlling it.
I'm happy to enter into this discussion with anyone, but as you can see, its a huge discussion! So I suggest we talk about only one point at a time
