Okay. I'll buy it. I am now imagining that at death there is simple extinction of the human being: body, soul and spirit.
It would mean that we would not get to see departed loved ones again which is quite sad but conversely, there is no fear of hell - and as far as heaven is concerned, how can you be troubled too greatly by missing out on something you have never experienced?
No. Not all that bad really yet atheists seem utterly sold out on the idea that all Christians are solely 'motivated by a desperate desire to get into an unknown, nebulous heaven.' - (Probably the avoidance of hell is actually a bit nearer the mark.)
It all comes down to your attitude. 'Pie in the sky when you die OR steak on the plate while you wait' as one old Pastor of mine used to say.
ALL of the atheistic creations of 'straw men' entirely miss the point. ALL these arguments are utterly trivial and not very relevant. Christianity is about entering a relationship with the Living Lord Jesus Christ - NOW. All that death really means is that this will then continue in different surroundings.
Little wonder that atheists haven't the faintest notion of what is actually going on!
