Here are some quotes from Physicist and Astronomers, Scientists, etc., that can start conversations. Instead of just throwing the quotes out like a challenge, it would be wise to research the topic enough so that you can answer the questions and comments that the other person will likely raise in response.
“The evolutionary establishment fears creation science because evolution itself crumbles when challenged by evidence. In the 1970s and 1980s, hundreds of public debates were arranged between evolutionist scientists and creation scientists. The latter scored resounding victories, with the result that today few evolutionists will debate. Isaac Asimov, Stephen Jay Gould, and the late Carl Sagan, while highly critical of creationism, all declined to debate.” — James Perloff, Tornado in a Junkyard (1999) p. 241.
“It was because Darwinian theory broke man’s link with God and set him adrift in a cosmos without purpose or end that its impact was so fundamental. No other intellectual revolution in modern times . . . so profoundly affected the way men viewed themselves and their place in the universe.” – Michael Denton, Evolution: A Theory in Crisis (1985) p. 67 [Australian molecular biologist].
“Unfortunately, in the field of evolution most explanations are not good. As a matter of fact, they hardly qualify as explanations at all; they are suggestions, hunches, pipe dreams, hardly worthy of being called hypotheses.” Norman Macbeth, Darwin Retried. (1971) p. 147.
