Are you working as a scientist? Scientific society tries to be objective in observations and findings, even though I can promise from practice that it is regularly not, but this is a topic for science philosophy. Nevertheless, it's always good to bear in mind the problems with science and the dominant paradigm we're living in.
If you objectively/critically look at the topic (do literature research), you will find sufficient studies which explored enough controversial observations where interpretations of a 4.5 billion years old earth just doesn't make sense. (extremely different dated age of skeletals in sedimentary layers with same radiometric dating methods, etc.)
Young earth creationists (6,000 years old earth) is, scientifically speaking, very unlikely also. I would advise people search good sources of dating methods and the critics on it as well as looking at explanations of the Taphonomy to understand more about it
But stating that it is crystal clear that the earth is 4.5 billion years old is not different (scientifically objective) than the young earth creationists talking about 6,000 years. Sadly enough, this is the current paradigm since (macro)evolutionary processes etc. need that much time to interpret their findings. Do research, think critically and find out for yourself whichever interpretation(s) make the most sense.
