I don't think that materialism automatically means no religion.
I've a pretty wide and vague definition of religion, so I imagine many religions will still be around,
Still, even the religions 'you might be meaning,
I expect will still be around.
. .
I don't know about 'size,
But I don't see the 'religion as too much at fault there,
Certain ideas just get popular, or not.
. .
Not 'so many worshippers of Greek, Roman, Norse Gods, I think,
'Still there are some.
. . . . . . . . . . . . . . . . . . .
I'm unsure what constitutes a better society and civilization,
I'm a bit torn between various ideas,
Still, I think it would be good if citizenship was a voluntary decision made later in life,
So some focus on freedom, I suppose.

Some religions have been crappy, some anti religions have been crappy.
Still, . . . How to view this practically. . .
Could assume we are given the choice of a new civilization,
Or hope of what a civilization might have turned into,
But if we go with the second scenario, atheist or religious, I find it easy to think of a good outcome 'somewhere,
. .
My concern with the 'new civilization, is people will adopt 'something,
Some laws, creed, values, religious or not,
And as my definition of religion is wide and vague. . . Mm. . Anyway I don't know.

I don't know if society would be better, if everyone was the same Religion,
It would probably be healthy to at least have an overlap of Values, Violent conflict otherwise,
. .
It is good to have many ideas in a society,
But some key Features 'must be assumed, Religious or not.
If all Atheist, well even Atheists disagree with one another,
It's more important to have the overlap of values/features,
Than the tag of Religious or Atheist I think,
. .
Religious Person 1 says help each other, Religious Person 2 says harm other,
Atheist Person 1 says harm each other, Atheist Person 2 says harm other,
I think many would see the value of help or harming, more important than the Religious or Atheist tag,
Though not 'all, some might see the other Religious/Atheist Person's Help/Harm as something to suffer through until there are no more Religious/Atheists, 'Then to go after the people who disagree on Help/Harm.

Some religions have been crappy, some atheists have been crappy,
Whether they burn people for supposedly being a witch, (Though it's more nuanced than that)
Or they guillotine people for being religious.

Plenty of religious people were into science,
Plenty of Science made great headway thanks to religious individuals and organizations.

Religious person values Z,
Religious person see's that many people are Y, suggests that by doing X, less people might be Y.
Analyzes how many people might be Y by action of doing X,
Does X if he thinks less people will be Y if he does X,
See's results, encourages or discourages X action.
'Thoughtful, I'd call a key feature.
Plenty of philosophy and religion say we value X for this or that reason,
How might we promote X?
Then test and think on various ways.
I don't think science and religion 'must be at odds.
