This is what I have come to believe over my past year outside of the Borg.
Early societies of mankind did not understand the world that they lived in. They feared it's natural phenomena and the fact that people grow old & die. In their limited understanding of the world they gave much of their wishes/prayers to these natural phenomena (it became there Gods)
Over the many thousand years since these so called God's had been established, they have been given nations & power through their long standing in our cultures. They now are 'real to masses of people.
Mankind, however, has evolved & grown up. People can see that natural phenomena is 'natural' & death is unfortunatly natural too. We can all pray as much as we can to the wind but we will still grow old & die.
The sad & horrible fact is that people want their god to be the 'all powerful one.'
They will kill, shun, hurt, anyone who states the opposite. And all this because they fear of nature.
So, to answer the question....No, there cannot be a true religion today.
Why? Because religion is not true.
