There are thirty Kalpas mentioned in the Puranas. Visnu in the Meghavahana Kalpa became a cloud and showered the earth for a thousand divine years, thus:
i. The Earth as a planet is as old as the Universe. It is remade by nuclear fusion during each Kalpa – its bedrock and molten centre reforming.
ii. The Earth is made habitable each Kalpa by Lord Skanda – the lord bearing all Shaktis; Living entities are recreated each Kalpa from Lord Visnu.
iii. The geological dating of earth rocks is determined by the half-life of radioactive elements; each dissolution causes material reformation of elements (fusion) and the atomic clock is reset. Thus science can only measure a Kalpa or 4.32 billion years – which in fact is the given age of the Earth according to geology. The sun, significantly, is 5-billion years old.
iv. The Earth, the solar system and every planet and galaxy in the Universe rejuvenates during Kalpas- this happens until the end of the Universe.
