INTRODUCTION

If you had discarded belief's false necessitation , you probably no longer have many worthless/sub-optimal attachments.

Of course, the mind of the non believer is an atheistic one. (Atheism: disbelief, or lack of belief in God or gods)

Pertinently , the mind of the non believer is a mind with no beliefs !

BEYOND DISCARDING THE CONCEPT OF BELIEF

I. MANKIND WILL PROBABLY CREATE MACHINES, WITH HUMAN-LEVEL BRAIN POWER

Life's meaning probably occurs on the horizon of optimization (See scientific source), and because artificial intelligence are non-trivial optimizers, the creation of human level artificial general intelligence is perhaps a non-trivial portion of life's meaning.

The human brain computes roughly 10^16 to 10^18 synaptic operations per second. (source a, source b)

Mankind has already created brain based artificial intelligence that achieve 10^14 of the above total (source).

Here are some exciting videos, showing how artificial intelligence exceeds mankind in many human, cognitive tasks: (youtube source a, youtube source b, youtube source c, youtube source d, youtube source e)

If mankind isn't erased (via some catastrophe), on the horizon of Moore's Law, mankind will probably create machines, with human-level brain power (and relevantly, human-like efficiency), by at least 2020 (See wikipedia exascale computing source).

II. AS SAM HARRIS THE ATHEIST SAYS, HUMANS WILL INEVITABLY MAKE ‘GODS’ OR GOD-LIKE MACHINES/SOFTWARE, AND IF WE SCIENTIFICALLY RECONFIGURE THE OLD GOD DEFINITION, HUMANS ARE 'GODS' TOO.

Of course, the God that Sam Harris is referring to (youtube source a, youtube source b), is quite disparate/different from theistic description; Sam is referring to the human level artificial intelligence as discussed in (i) above.

Like how we have come to know old mythical concepts for what they really are through science (See source), while being entirely atheistic, we can perhaps come to know the God concept in the regime of science, all while still being entirely atheistic.

A possible scientific redefinition: God is any non-omniscient entity with the ability to compute simulation(s) of universes (from crude universes i.e. illustris, to perhaps instance(s) that may contain sophisticated intelligence) and or to engineer non-trivial intelligence (perhaps artificial), that shall exceed that of the intellect of its creators..

III. HOW TO BECOME A MORE CAPABLE 'GOD'

Here are three steps for how to become a more capable god, on the horizon of the scientific definition in (ii):
