Time exists in physics, but the flow of time does not. Physicists do not understand the flow of time. In any given coordinate system, we can be at rest in space, but in that same coordinate system, we cannot be at rest in time. Time has this qualitatively different feature. It progresses.
This movement is currently ignored in physics. The relativistic transformations show that rotations in space-time wind up converting spatial coordinates into time, and time into space. But the space time diagram does not include any sense that time flows, that it is different. It has no special time location for "now" -- a moment of time that is central to our sense of reality because it divides that reality into two realms: that which we cannot influence, and that which we can.
Here is a quote from my upcoming book Now - The Physics of Time: "Brian Greene in his book The Fabric of the Cosmos suggests that relativity “declares ours an egalitarian universe in which every moment is as real as every other.” He says that we have a “persistent illusion of past, present, and future”—a perspective reminiscent of Augustine. He concludes that because relativity doesn’t discuss the flow of time, such flow must be an illusion, not part of reality. To me this logic is backward. Instead of insisting that theory explain what we observe, this approach implies that observations must be twisted to match the theory."
Einstein despaired of his inability to explain the flow of time. But Einstein, despite his despair, moved forward and showed that the rate of the flow of time depends on both velocity and gravity. That suggests strongly that the flow of time does not originate in the human mind, but has a true external physical reality.
Another quote from Now: "Space and time together provide the stage on which we live and die; it is the stage upon which classical physics makes predictions. But until the early 1900s, the stage itself wasn’t examined. We were supposed to notice the story, the characters, the plot twists, but not the platform. Then, along came Einstein. His great genius was in recognizing that the stage was within the realm of physics, that time and space had surprising properties that could be analyzed and used to make predictions. Even if he despaired of understanding now, his work is central to our understanding. Einstein gave physics the gift of time."
Your question is very deep. We need to think about the origin of time's flow. Einstein opened such questions to physicists.

ब्रह्मा विष्णु महेशाद्या यस्य अंशा लोक साधकाः।
तं रामं सच्चिदानन्द नित्यं रास ईश्वरं भजे।।
~ I adore that Ramchandra always, Who is a form of sat-chit-Anans, Expert in Raas leela and Whose portions are Brahma, Vishnu, Mahesvara.
(Hanumat sanhita)
यस्यांशेन एव ब्रह्म विष्णु महेश्वरा अपि जाता महाविष्णुर्य्यस्य दिव्यगुणाश्च ।
स एव कार्यकारणयोः परः परमपुरुषो रामो दाशरथिर्वभुव ।।
~ Whose Portions are Brahma Visnu and Mahesvara, Whose divine Guna is Mahavisnu,The one who is the cause of all causes, The one who is higher than the highest, such is Ramachandra, the son of Dasratha.

Self-realization is one of the major pre-requisites to attain ultimate enlightenment and liberation (moksha). Self-realization means peeling away fabricated layers of one's own personality to understand the true self and hence the true nature of reality.

वदन्तु शास्त्राणि यजन्तु देवान्
कुर्वन्तु कर्माणि भजन्तु देवताः ।
आत्मैक्यबोधेन विनापि मुक्तिः
न सिध्यति ब्रह्मशतान्तरेऽपि ॥ ६ ॥
Let erudite scholars quote all the scripture, let gods be invoked through sacrifices, let elaborate rituals be performed, let personal gods be propitiated- Yet, without the realization of one‘s identity as Self(Brahman), there shall be no liberation for the individual, not even in the life times of a hundred Brahmas put together.
~ Adi Shankaracharya

“Let the truth of Brahman be taught only to those who follow Dharma, who are devoted to Him, and who are pure in heart. To the impure let it never be taught.” (Mundaka Upanishad, 3.2.10)
