God knows. Also, it is clear in the Bible that the Creator is in management of any and all things. And we can be personally ruled by Him in His own peace >
"And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful." (Colossians 3:15)
He is the One who created all things, and maintains their existence, plus He is almighty for dealing with "the spirit who now works in the sons of disobedience." (in Ephesians 2:2) And He is able to personally communicate to have us know what He pleases for us to know.
And Jesus His Son came to this earth and suffered and died for us. I do not know of any other who is able in me to personally and more and more constantly rule me in His own peace which shares with us His own almighty immunity against wrong drives and unforgiveness and ongoing emotional suffering and anger and arguing and complaining and other dominating and cruel things.
Jesus guarantees us that if we learn to obey Him and love the way He wants, "you will find rest for your souls." (in Matthew 11:28-30)
And, of course, Jesus rose from the dead on the third day and now is Lord of all. Jesus Christ is the way and the truth and the life > John 14:6 > and He says, "No one comes to the Father except through Me." And no other has done these things for me, that the Bible says God does. He has not communicated to have me know of any other, while personally guiding me in His own peace.
And it looks like you are admitting how you don't know this. Only God can prove Himself to you.
It is like how I could tell you all about elephants, and all you have ever seen is a walrus. I can say an elephant has tusks, and is very large with wrinkly skin. And all you can get is I must be talking about a walrus.
Or, you can spend all day saying, how do I know I have experienced an elephant? And why hasn't an elephant come to my igloo and introduced itself to me? You can second-guess, I see, anything I offer. But this does not change if there is really an elephant or not.
If you have not experienced God, it is because what we do does not work. We need how God has us come to know and share with Him. But in pride we have the personal communication of God's resistance >
"God resists the proud" > in James 4:6 and also in 1 Peter 5:5. Every one of us has done foolishly in pride; so every one of us has experienced God personally communicating with us by means of His resistance, whether we know this or admit this or not.
My opinion is you can not present a quote of any other being who claims to personally and constantly, more and more, guide that one's own children in perfect peace, nor can you quote any other who claims to personally resist any and all wrong humans in their pride.
Only God through Jesus makes this claim, as far as I know. And I mean in writing, clearly recorded and known around the world. And He has provided His own Son to suffer and die for us, so we may be reconciled with Him, after we have lived so awfully and selfishly against Him; and now He is deeply correcting our character so we become natural in loving any and all people > Hebrews 12:4-14.
Because He is in control of all, He can use even hypocrites to print His word and spread this message around the world. He is not in some hidden sneaky who-knows-where and not heard of wherever, like it seems is the case of certain ones you have listed that I have never heard about, at all . . . if even any real number of humans beside you have ever heard of them.
Jesus is so credible, that many people are trying to counterfeit Him so they can deceive people. You can't use people very well, by using what is not a counterfeit of real money!
The truth is, for me, I am not God; so how can I know whatever, unless He has me know? He is so more and better than we are. An ant in the bottom of an ant hill can not know if I exist. But I can dig up the ant and then it has proof. But, even then, the ant is not me; what really can the ant know if only it is in my hand??
But God's word says that in Jesus we are "joined to Him" so we are "one spirit with Him" > in 1 Corinthians 6:17. And since we do have our spiritual level or sort of existence, we can connect with God who is spiritual in being, and even be changed by Him in our character so we become able to share with Him, even feel what He is feeling.
And God's word says to have "the incorruptible beauty of a gentle and quiet spirit, which is very precious in the sight of God." (in 1 Peter 3:4) So, from this I see how God's love is gentle and quiet. So, in His gentleness and humility, of Jesus, I can share deeper than words with God Himself in me.
But this comes with getting rid of my noisy anti-love stuff >
"Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you." (Ephesians 4:31-32)
God's grace changes us to succeed in getting rid of noisy stuff of unforgiveness and dominating drives for pleasures and excitement which only waste us and our time away from finding out how to love. There are many anti-love things which so keep us from enjoying God and loving any and all people. But Jesus died for us, in order to get us started in discovering how to share with God and learn how to love any and all people.
But people stay in their dominating and dictatorial stuff which keeps any of us from sharing with God. Only Jesus can save us and correct us from and cure us of this. I know of no other who does this and has guaranteed this in writing which has been spread and studied around the world, in various cultures.
All others that I have heard of are distant, and/or expect humans to take care of things, themselves, in self help efforts.
Only God through Jesus is recorded to claim He personally cares for His children, while we live in submission to how He rules us in His own peace which is almighty against fear and fighting and arguing and unforgiveness and dominating and dictatorial drives for pleasure. And, instead, Jesus gives us "rest for your souls" (Matthew 11:28-30) while we do what He has us doing. And I do not know of ones of any other who openly and regularly write and talk about how their god more and more constantly does anything like this with them.
