Thank you for your numerous comments and statements
Unfortunately I cannot answer to every one, because it would take too much time Moreover I cannot answer only in one sentence

First of all In Christianity there are not three Gods

There is the only God, figured as the Father, then there is his Son Jesus and then there is the Spirit

You are open to define what this means, spirit can be characterized as the message of humanity, being in all of us, preferably filled with ethical comprehension and recognition


Second of all, I am a Christian (evangelischer Protestant) Our belief is open-minded and not narrow-minded to the Bible only, we are not bond to the Bible, because in our belief the Bible is not given nor written by God, but human-made

This implies that the Bible is a book as a pattern of thinking, it suggests you advice, it suggests you proposals
According to our moral, ethical view, our education, our knowledge we are free to think what we want, but we are responsible towards ourselves as well as towards other people

Now to the central question, someone of you has put

Why are humans created according to Christianity?

Yes, this is a very complex question and as complex is the answer

The answer depends on your approach

A theologian would answer that humankind is created to exist and produce on earth associated with the problems that normally arise between humans and also acknowledging that there is a vis major, mostly called God

A scientist would answer that humankind has the knowledge to exist on earth and to make use of all the science

A sociologist would answer that you have the responsibility for yourself and for the society of humans

There are more answers or you can choose to take a little or all of them, but in the end it is your own opinion.

Regarding religion I confirm that thinking about humankind, nature and science you cannot be ignorant and you have to put questions. But the answers vary, from your point of view and so do religions also

But you cannot claim that one answer is the only right one. Ok, you can pretend for your behalf to have found the one and only answer, but that is only your opinion


As long as it is your opinion I accept it and I do not have any problems with or against that, but I cannot accept that some people proclaim to have found the one and only right answer
