I understand fully. But the data is collected and cherry picked according do propaganda needs. Humans have been on this planet about 50,000 years (in our current form... Two Great Years) and life has existed in this Universe for many Kalpa.
This current age of Kali Yuga will eventually result in humans living about 20 to 30 years with the exception of those who are serving the Creator. The Kali Yuga started about 5,000 years ago. It is known as the Age of Quarrel in English.
General Overview
After Dwapara Yuga comes Kali Yuga the age of darkness, when spirituality is eclipsed by selfishness and dogmatic materialism. While Sri Krishna remained on the planet, Kali Yuga could not begin. The reason is that the presence of the Supreme Person keeps ignorance and irreligion at bay. As the Vaisnava poet Krishnadasa has written:
kṛṣṇa — sūrya-sama; māyā haya andhakāra yāhāṅ kṛṣṇa, tāhāṅ nāhi māyāra adhikāra
“Krishna is compared to sunshine, and māyā [illusion] is compared to darkness. Wherever there is sunshine, there cannot be darkness. As soon as one takes to Krishna consciousness, the darkness of illusion will immediately vanish.” (Caitanya-caritamrta, 2.22.31)
However, shortly after the departure of Sri Krishna to His own realm in the spiritual sky, Kali Yuga broke out in full force. The social order was turned on its head. Instead of educating and protecting the populace, religious and political leaders abandoned virtue and became the chief criminals in society. The Vedas describe many events of Kali Yuga in great detail.
In Kali Yuga, or the Iron Age, spirituality and morality are diminished to shadows of their former selves. Deception and hypocrisy in the name of religion is the status quo. The only process of dharma that is still practiced and effective is nama-sankirtana, or chanting the names of God, especially the maha-mantra: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.
As the Dark Age, Kali Yuga is the polar opposite of the Golden Age, Satya Yuga. During Kali Yuga, the world is virtually devoid of peace. All living beings suffer material hardships as they struggle simply to survive, being deeply afflicted by fear.
In Kali Yuga, people live up to only 100 years. The Bhagavata Purana describes human beings of Kali Yuga as follows:
“In this iron Age of Kali men almost always have but short lives. They are quarrelsome, lazy, misguided, unlucky and, above all, always disturbed.” (Srimad Bhagavatam, 1.1.10)
