You were put here on this earth for a reason: to know God and to experience Him. And without God, there would be loneliness, there would be yearning, there would be desperation. The ultimate cure to loneliness is simply this: God. He is the reason for life, He is the purpose, and without Him, we would have nothing and be nothing.
Albert Einstein once said
“if you cant explain it simply, you dont understand it well enough”
