'Life is meaningless,' as everything else is meaningless. Is not it also true 'to live alone' is meaningless? That is wny two, or more, are always better than one, isn't it? And this is why, perhaps, God has created man and everything else in the world, the heavens and the universe.
If you've been reading the book 'ecclesiastes' where the word 'meaningless' has been repeated 38 times, you will understand how King Solomon, the wisest and wealthiest man in the world during his time, described how 'meaningless' life can be without God. If you do not agree with this, that's your right and prerogative.
Sooner, when you get really sick, lonely, weakened in health, somehow, you may realize the importance of this message in ecclesiastes, and the truth in God's words in Christ Jesus, that you may find lasting and true peace, joy and happiness in your heart and spirit.
In this short and temporal life, is it worth the thought?
