At most, You exist for 80/90 years, and you don’t exist for ∞ – 80/90 Years. Do you think your existence makes any difference to the period you don’t exist? Assuming you were born for a noble and great purpose to do some great things is an idiotic self-consoling assumption. Your existence is worth absolutely nothing.
If God created time & space, he would be beyond Time & space, that means if any religion talks about a judgment day where god’s presence is mandatory to judge your deed, is pure stupidity. God would not need to wait for a time till the end of this universe to judge you.
