Science is answering our pondering about our place in the universe. We can also be scientists and create a moral belief system that’s not based on God.
That wouldn’t be science. It would be a religion.
For most of history science was done by the religious because few other people were literate. We long ago decided it would be better to have people specialized in science, and separated science from religion. And it worked really well.
Now you want to turn science into a religion? We already know that wouldn’t work very well. Why would you want this? It seems to me you’re not really against the concept of religion you just don’t like the religions we currently have.
Science isn’t about beliefs. It depends on people being skeptical of everything. Searching for empirical evidence that’s contrary to current theories so those theories can be improved and sometimes even replaced. Science is a process. Mixing morals and beliefs into science makes for bad morals and bad science.
