Where is the modern day proof that Yahweh is a living being. Tangible proof?

there's a seminar on Youtube i think you should watch. it will give you the ultimate proof that the universe was created by an intelligent designer and not the big bang. the video is called "creation seminar 1 - Kent Hovind - age of the earth" the seminar is about two and half hours long but it's a good one and it will give you the proof you're asking for.

at least watch the first thirty to forty five minutes.

In the Bible (I will not cite the verses since you requested for it), there are many predictions and promises that God did since the world began up to our modern times. And as a part of His real organization and being guided by His holy spirit, only the part of this org. and the people who lined up for His will can see and feel it.

Want to answer it using Science.
The basic unit of living things is the cell, and the basic material that makes up a cell is protein. Evolutionists acknowledge that the probability of the right atoms and molecules falling into place to form just one simple protein molecule is about 1 in 10113, or 1 followed by 113 zeros. In other words, it could take 10113 chances for the event to occur once. But any event that has one chance in 1050 is dismissed by mathematicians as never happening.

However, far more than one simple protein molecule is needed for life to occur. For a cell to maintain its functions, some 2,000 different proteins are needed. What, then, is the probability of all of these happening at random? It is estimated that it is 1 in 1040,000, or 1 followed by 40,000 zeros! Are you willing to rest your faith on such an outrageously remote probability?

If the probability is so remote for a cell to come into existence by accident, it would be even more so for the cell to evolve into the great variety of complicated living things. The fact is that between humans and beasts, there are differences far greater than the obvious physical ones. Man is endowed with a conscience; he has feelings, aesthetic values, moral concepts, thinking ability, and reasoning powers. Animals do not possess these capabilities. If man evolved from the animals, why is there such a huge gulf between man and beast? This is another thorny problem for the evolutionists.

You're the tangible proof that Jehovah God truly exist. The human body, your body, is amazing, wonderfully made and "awe-inspiring" (Psalms 139:13-16). Scientist and Biologist are amazed at the human body's ability to have so many "back-up systems" in case of sickness or trauma to the human body. Think about that amazing "universe" in your head, the brain. The more scientist and those who study the human brain examine it's functions and operations, the more they are stunned at the workings of this stunning, amazing creation of Jehovah.

Many scientific scholars are driven to admit that great deliberation, wisdom, power, forethought and love was put into all of God's creations and therefore, He, God, must exist (Romans 1:20).

The very things you say you don't want to receive answers to, like look at the universe biological complexity, are the very answer to your question. You see these things everyday. You accept without a thought, the power of the sun, the law of gravity, sound waves, emotions, all things you can't really see but you see and feel the effect and therefore proves its existence. If you were blind, how would you know a person is real, can a blind person fall in love? We see with our brain, and "through" our eyes, not with our eyes. Seeing or evidence of something, goes much further than just "seeing" it involves our power of reason, discernment and evidence. You have all the things in front of you along with the bible to add further proof.

I would also say this.. how about address the personage of God through prayer. Address him by his name Jehovah and end your prayer in the name of your son Jesus Christ. If you sincerely want to know he is alive, and cares about you ask him sincerely to show himself to you. He will!
