2. God's Existence is Unconditional
Yesodei HaTorah 1:3
Even if nothing else existed, God would still exist. Doing away with everything else in the universe would not affect God because everything else requires Him to exist but He does not require anything else. Therefore, the reality of God’s existence is different from the reality of anything else’s existence.
Yesodei HaTorah 1:4
God’s objective, independent existence is referenced in Jeremiah 10:10, “Hashem, your God, is true." This means that He alone is true. No other being possesses a truth like His truth. This is what the Torah means when it says, "There is nothing else aside from Him" (Deuteronomy 4:35). There is no being with a true existence like God’s.
