How Do You Know God Exists

What proof is there that God exists? What do we respond to a person who questions God’s existence? What is the ruling on this from an Islamic perspective and paradigm? Wouldn’t it be nonsensical to enumerate the uncountable proofs all around us that show us the same? What is Fitrah or the spiritual DNA of a person inclined to do? There is no God but Allah (SWT). What can we take from the Qur'an and Sunnah on proving that Allah (SWT) exists?  Also, what scientific proof can we give to one asks this question? Shaykh Yasir explains what would be the best way to handle these questions.
