God’s existence has never been effectively challenged, but has only been further made strong in 21st century

Some people asking proof or existence God has nothing to do with God or His existence. False impression was created that existence of God is not proved by Science. But Science is neutral, cannot be used to prove or disprove existence of God the immaterial. Its realm is MEASURABLE facts while God and spirituality is all about IMMEASURABLE facts, about how to deal with fellow-humans softly and sweetly, according to major religions, from religare [Latin], “to reconnect,” bringing harmony between all living beings. In reality, existence of God was not disproved by putting human thoughts into the mouth of Science and by making CATEGORY ERROR [which is also predicted by God].

Subject of God is for the relaxed people who have enough time to ponder over what they see and would not tell others “We will give you our precious birthright, and on behalf of us kindly define Self [Am I from animals or God?], God [Supreme Father], earth [our only habitat], Drama of Life and its Ruler [Law of Action and Reaction] and its purpose. Such ones have noted or can note the below given truths about God:

1 ) God's existence is a settled issue when a person mindfully observes this earth [our only home], like a dew being maintained at the core of sun. Earth is made LIFE-SUPPORTIVE in this too incomprehensively vast HOSTILE universe for which “there is no center — or edge.” (astronomy com) For this supreme skill of God, no comparison is possible with humans as shown below:

With all the skills and advanced knowledge of all scientists being put together along with their most sophisticated labs available today, life cannot be made even in FAVORABLE environment, //www.reddit.com/r/biology/comments/1f3axdd/how_close_are_we_to_creating_life_from_scratch_in/. Hence question of whether can we show in a lab “How life AND life-support systems arise in HOSTILE environment?” is not only impossible but also unthinkable! (Google the question “Why can't life be made in laboratory until now?” you will be amazed to know how much we did not know).

To add to the glory, life-support systems are not just mere mechanical that will go into shutdown at one point, but they are cyclical—with no beginning and no end. Among such life-supports, TREES are WONDER of all wonders as they exist eternally through seed-mechanism in whose memory all its infinite number of future generations remain protected. And simultaneously trees are also true SILENT PREACHERS about God and are also giving us numerous and valuable SPIRITUAL life-lessons designed to make our life at ease and peace, //www.reddit.com/r/DeepThoughts/comments/1qn8b49/god_knows_nobody_on_earth_really_doubts_his/. What trees preach is unmistakably true, simple and beneficial and is immune to corruption and tampering, hence religions and their Scriptures [with more resemblances and less differences] can be treated as mere secondary help.

2) Besides God also predicted global events as signs of Last Generation such as global wars [two are already over with final one being in the preparation], pollution and its resultant “tossing (salos) of the sea” (Luke 21:25, Greek Interlinear, full verse under footnote) or “Swelling of the Seas [also called SEA-LEVEL RISE]” and they are all happening before us. The Greek word "σαλος (salos) derives from the Proto-Indo-European root "tewh," to swell, from which Latin gets tuber, a hump, and protubero, to swell (hence the English protuberance)." (Theological Dictionary, Abarim) "Swelling of the sea" is God's terminology with DEPTH, and modern term is "Sea-Level Rise," //www.reddit.com/r/exjw/comments/1qqyf1x/the_most_prestigious_prediction_of_god_which_jws/

3) God will be a subject of “ridicule” is another prediction for the Last Days. (2 Peter 3:3, 4) While ONE-sensed trees are always full of praise for God and servers of humans, it is quite NATURAL for MULTI-sensed humans to become even more zealous praisers of God and to be even more serving others. Yet its opposite scenario is predicted. (2 Timothy 3:1-5; 4:3, 4)

Growth of unbelief into global proportion is also predicted in the Book of Revelation. While this Book is about how Last Generation will climax in Final Global War and its survival into New Age, it also speaks about symbolic “blasphemous” entities winning people globally to be blasphemous, to reject God in favor of materialistic teachings. Its chapter 13 shows how mankind easily accepts “six-numbered arrangement” of species in exclusion of God. Through curriculum syllabus, people are forced to accept existence of only ONE-sensed trees, TWO-sensed worms, THREE-sensed insects, FOUR-sensed reptiles, FIVE-sensed fishes, birds and animals, SIX-sensed humans, whose physical resemblance is interpreted as evidence for evolution, thus conveying the message that GOD IS NOT NEEDED, thus making the ism godless or “blasphemous,” https://www.reddit.com/r/DeepThoughts/s/bY6yTqI8lV.

Thus even increasing disbelief about God is also the proof for His existence as this too has been predicted. It is typical about concluding phase of this Age which will see increasing number of unbelievers which, means, earlier the history more and more people would be believers—just like old and decadent palace has a glorious past. Whatever happens in the concluding phase reveals just the opposite for early history. For example, we replace trees with concrete jungle (deforestation-world-losing-area-forest-size-of-UK-each-year/guardian .com) precipitating climate emergency. In contrast, ancient Indians were taught to treat “a tree as equal to ten sons.” (Matsya Purana 154.505 to 154.512). 

Yet the same sight of ONE-sensed trees makes true believers even more spiritual. Trillions of trees inspire them to ask themselves: “If ONE-sensed trees are such great servers giving too valuable physical things and spiritual lessons to the society yet taking only wastes from society, how much more SIX-sensed human beings should do so. Accordingly, they experience “never-ending waves of peace” as promised by God which only increase their belief even more. 

4) Similar proofs are plenty for those who want them,  //www.reddit.com/r/DeepThoughts/comments/1n3tmtt/hardest_proof_for_existence_of_god/.
