Is God real? How can we know?

 God is the eternal origin of all that exists, so if He doesn’t exist nothing would exist, and things exist.

If you want to know that He is real then I suggest doing what God says to do in Bhagavad Gita to know He is real.

The Supreme Personality of Godhead said: Now hear, O son of Prtha, how by practicing yoga in full consciousness of Me, with mind attached to Me, you can know Me in full, free from doubt. Bg 7.1

Iskcon aka The Hare Krishnas is a society dedicated to helping those interested to “practice yoga in full consciousness of Krishna with mind attached to Him.”

No doubt some people will tell you that there is no evidence of God, zero, nada, zilch, blah blah blah, so ask them if they have practiced yoga in full consciousness of Krishna with mind attached to Him. Not for for ten minutes but ten years.

CERN approved construction of the Large Hadron Collider in December 1994, and the machine circulated its first protons on 10 September 2008. Only in 2012 did CERN announce they had found ‘The God particle’. Before that it was theoretical but not yet directly observed. Zero, nada, zilch. Because scientists wanted it to exist to substantiate the standard model it was explicitly listed as the primary reason for the LHC. When it was found it was a cause for celebration for many, and a cause of disappointment for others who would have preferred that it hadn’t been discovered.

If everyone had said there’s no evidence so there’s no point in investigating, then it’s unlikely it would have been found. Instead The Large Hadron Collider involved an enormous global effort: more than 17,000 scientists from over 110 countries contributed, and the construction cost was about €7.5 billion (≈$9 billion). This figure covered the accelerator itself and the massive detectors, with ongoing upgrades like the High-Luminosity LHC adding billions more. And after that extraordinary effort they found direct evidence of it.

So do you want to side with the “no evidence - don’t bother with it” people, or those who are a little more adventurous and industrious and want to see for themselves? You know, the science-minded people who think: “Here’s a claim, here’s the proposed method of investigation, and here’s the claimed result. Let’s try it.” A lack of direct observation is a pretty poor reason not to investigate, as demonstrated by the LHC.
