One way to solve meaninglessness is to be part of something larger: a political or social cause, providing a better life for your children and their descendants, or becoming a religious servant of God.
However, even if one’s life is given meaning by being part of something larger, that larger thing could not escape the question—what is its purpose? Either it has a purpose by being part of a larger thing or it doesn’t have a purpose. If the larger thing which our life is attached to is pointless, then it should be okay to accept that life is inherently meaningless. Such is the reason why Using God as the ultimate purpose is problematic.
