When a lot of atheists online say, "there is no scientific evidence for God", they don't have a correct understanding of science.
They seem to think that because science does not investigate God that therefore it is significant if it finds no evidence of God. But in fact it follows that there is no evidence for God scientifically BECAUSE science does not investigate the supernatural.
In other words, a theist can just as easily make a similar assertion; "there is no scientific evidence God doesn't exist."
Both statements mean nothing.
And since science does not investigate supernatural claims, you can't say the absence of evidence is meaningful without making an ipso facto, tacit declaration that science HAS investigated God. Or, that you the atheist, have investigated God on science's behalf.
LOL.
Anti-theists really can be rather dense.
In case you still don't get it, science is not "atheism", therefore when you say there is no science to God you are appealing to yourselves as an authority on science. (argumentum ad verecundiam, because atheists are not an authority on science, as their declaration is proof enough that they don't understand science very well.)
