who needs who is what a man said.  obvious he do not understand the teachings of buddha.
a stone does not need anything. just exist with time and disappear with time.
一切有为法,如梦幻泡影,如露亦如电,应作如是观

does he understand this.

Everything is meaningless

I am not so sure if the stone will vanish. Leave it at a corner and it will still be there long after you and I are gone from this Earth. And it was there long before our forefathers came to Singapore.  That which has no life cannot lose what it does not have. 

The stone along with the sand, the so-called precious stones and minerals and whatnots are collectively what make up the planet Earth.

It has a purpose as part of Creation. Without it and the rest, there's no Earth and then after God created all the things which had a life, where would they exist? Floating about in space?

All things, living and non living, are meaningless apart from God.. but once we return to Him, everything will become meaningful, whem they all fall into place.

Do not rely on philosophy to try to find or understand life and its purpose and meaning. Sages from ancient Greece, India, China had gone through that, searching without realising it, that they were searching for God. The Bible tells us that we don't have to search anymore because through Christ, God had made it possible for us to be reconciled with Him. Amen!
