@Jasper10,
Three observations,
1.How can atheists assert anything if they don’t exist? It may be possible but how?
2.If they have a dualistic reasoning biological computer brain I would suggest that it is possible to make the assertion “I don’t exist” but it will always be contradicted by the assertion “I do exist” because we know from personal experience that this biological computer brain can’t make its mind up.It’s honest.It doesn’t know.
3.We know that natures magnetic force interactions NN,NS,SN,SS don’t cancel out, they only balance out, hence the vibratory balance found throughout nature.I would suggest that this is the foundational reason for the biological computer brains dualistic logic outlined in item 2.
