If there is scientific consensus we've discovered the first extraterrestrial life form, will it be silicon based?

Prediction market on manifold. Link: https://en.wikipedia.org/wiki/Hypothetical_types_of_biochemistry The element silicon has been much discussed as a hypothetical alternative to carbon. Silicon is in the same group as carbon on the periodic table and, like carbon, it is tetravalent. Hypothetical alternatives to water include ammonia, which, like water, is a polar molecule, and cosmically abundant; and non-polar hydrocarbon solvents such as methane and ethane, which are known to exist in liquid form on the surface of Titan.
