Mathematics Is Universal. It's Discovered By Human

Science, We Are Repeatedly Told, Is The Most Reliable Form Of Knowledge About The World Because It Is Based On Testable Hypotheses. Religion, By Contrast, Is Based On Faith. The Term 'doubting Thomas' Well Illustrates The Difference.

It's Worth Remembering That All Technology Leaves A Footprint. For Example, Our Own Technology Is Leaving A Footprint In Terms Of Global Warming, Which Could Be Detected From A Long Way Away. One Assumes That A Very Advanced Civilization That Has Been Around Maybe Millions And Millions Of Years Would Have An Even Bigger Footprint That Might Extend Beyond Its Planet To Its Immediate Astronomical Environment.

We Might Expect Intelligent Life And Technological Communities To Have Emerged In The Universe Billions Of Years Ago. Given That Human Society Is Only A Few Thousand Years Old, And That Human Technological Society Is Mere Centuries Old, The Nature Of A Community With Millions Or Even Billions Of Years Of Technological And Social Progress Cannot Even Be Imagined. ... What Would We Make Of A Billion-year-old Technological Community?

The Laws Of Physics ... Seem To Be The Product Of Exceedingly Ingenious Design... The Universe Must Have A Purpose.

If We Do Discover More Than One Type Of Life On Earth, We Can Be Fairly Certain That The Universe Is Teeming With It, For It Would Be Inconceivable That Life Started Twice Here But Never On All The Other Earth-like Planets.
